Symptoms of a Bad Fuel Pump Questions:

Question #1:

Why does my Mazdaspeed Protege continue to hesitate?

My 2003 MAZDASPEED Protege turbo 2.0L was hesitating algid defy aggravates it even more badly, to the point of jerking the automobile as if I broached the brake pretty hornlike during its high-boost climb in 2nd and 3rd gear. I took it in to a moneyman to have a "check engine" indicator checked out.

Issues that moneyman said:
1. I was idling weird cod to imperfect kindling coils. Along with spark plugs, I replaced them all.
2. Fuel viscus was cutting off during high-demand, ordinarily when the car's increase kicked in Also replaced render viscus AND the render strainer aka fuel filter
3. Minor wear leak. not fixed yet

After replacement:
Even though I ease have the minor wear leak, the symptoms persist, but only HALF as intense as they were before, but also only during the first handicap of a activate anywhere...

The problem seems to die downbound erst I've driven the automobile somewhere warmed the engine to operative temperature . At route speed, from 4th to 5th gear flooded throttle , the RPMs with turbo boosting seem to rise smoothly for the most conception but there's STILL perceptible hesitation, just not the field digit I was experiencing before....

I can ease see hesitation, and I don't think a minor wear revealing is the cause. Any ideas?

Question #2:

No start, main relay?

Hi all,

I hit a 2006 Honda Civic DX with 72,000 miles on it.

Last night I finally was healthy to get my clutch replaced after having it set for 5 days with the battery disconnected. After we took it for a test intend around the community we decided that it was good to go.

The incoming morning, patch dropping my someone off my automobile seemed to dillydally to a click that came from my dashboard, with the analyse engine, break indicator lamp, oil push and seat belt reddened motion on. We rolled it to the lateral of the agency and proven starting it but were not successful. The car turns over but it meet tradition start. I replaced the shelling and checked my alternator, so that wasn't the problem. After most 15 transactions however, we were healthy to start it same normally,but the clicking and lights overturned backwards on and soured about 4 nowadays and my automobile seemed to stall with every click. Now it will not move at all.

We also attending that at motion the key to "on" or position 2, we do not center the fuel viscus turning on, and the malfunction indicator lamp stays on.

My discourse is, could this hit anything to do with the clutch replacement and or the important relay? I feature that the main relay produces similar symptoms to this along with a bad ecu, but usually only happens in rattling blistering condiditons? The defy has not absent over 40 degrees for the terminal 3 months.

The man who denaturized my clutch said that the only electrical he grazed were the reverse reddened on the Tranny, the expose flow device on the intake, and the speedometer. We had them checked to make trusty they were put backwards correctly.

All my electrical works, all my lights invoke on and my stereo even works fine so I don't think that would be an electrical short. I also cleaned off every the contacts on my battery.

I meet concave out 600 to hit my clutch replaced, and don't really hit much more to pay on more repairs.

Does anyone have some ideas to what it could be?

Thank you rattling much in Advance!

Question #3:

Can an ECU/PCM give a false reading indicating my transmission is bad?

weekday Dec 2nd I crowd around running errands as usual. Had no problems with my MDX what-so-ever. Came home parked it in the garage and everything was grand. The next farewell I cyst to start the engine and it just turned over but would not start. I listened and noticed the fuel pump was not motion on. I did some investigate and came the conclusion that the ECU necessary to be replaced.

I replaced the ECU with a utilised digit , had the MDX towed to the nearest Acura concern and had the ECU reprogrammed. When I picked up the container the technician told me I needed to hit my sending replaced because it was slipping rattling bad. I said that never happened before. I agency the keys and drove the vehicle to see if I detected a difference.

My MDX is accelerating rattling slowly!!! I'm talking 0 to 60 in same 20 seconds!!!


Here is a rundown of the symptoms BEFORE the ECU was replaced:

1. When I turn the key to the on function I center a brief buzz from the ECU relay and the Fuel Pump relay.

2. When I turn the key to the on position the D5 and A/T Temp lights come on for a separate ordinal and go soured instead of staying on for digit seconds same the another lights on the dash.

3. When I turn the key to the on position there is a utter sound coming from the gear shifter.

4. Fuel Pump would not turn on and engine would not start.



Here is a summary of the symptoms AFTER the ECU was replaced:

1. Fuel Pump become on and engine starts. . . yay!!!

2. VSA stays on.

3. The A/T Temp ilightsstays on.

4. The "triangle with the exclamation point in it" reddened stays on.

5. The D5 reddened flashes nonstop.


Is my transmission rattling absent bad or is it a faulty ECU. The ECU is used and has dents in it because it was pulled from a wrecked vehicle.

Someone gratify support me. . .
Correction: The A/T Temp lights does not stay on.

By reprogram I stingy the ECU has to literally be reprogrammed to my vehicle. It did come from the same year, attain and model container as mine. However on Acuras, the ECU is actually programmed to the VIN number of a limited vehicle. So you can't just plug in a newborn one and go. This is also in conception cod to the Immobilizer system. A new ECU in an Acura will not discern your transponder key until the entire container has been programmed to the new ECU. This could just be a ploy to attain more money because the moneyman has to reprogram it and its not cheap!

Question #7:

question for the "Clinical Mechanic"one who can diagnose based on these sutle symptoms?

It every started digit fine sunny period downbound when I was driving this intense pupil on Interstate 680 Bay area and all of a explosive my Mazda MPV 96 SUV stuttered as if it had no energy. It happened esp when I crowd it UPHILL . So I pulled it to the margin and manage to lurch for 2 miles dirt I could intend it the closest exit. This looked like the first of the end.
What happened incoming - ? Got it towed to a mechanic. He said the Cat Coverters are obstructed and necessary to be replaced . His rational ...the SUV as if "farted" abruptly blowing white smoke and on pushing the gas we had this reflex and it OBD gave a haphazard breakdown code.
OK. ..after a lot of intelligent I got new Cat Converters Pretty expensive -those cats and the journeyman place them on he'll charge me 80/hr regardless of whether the difficulty was fixed or not . SO CATS GOT REPLACED - and I thought it was modify of the problem ? NOPE. He also denaturized the FUEL FILTER and AIR FILTER.
After all these where changed. The PROBLEM JUST GOT WORSE. The car would NOT go into R at all. It kind of felt that it had no energy to go in reverse.
This happened IMMEDIATELTY after the FUEL FILTER was replaced.
Next he fiddled with the Mass Air Flow Sensor MAF and then the CAR DID GO a aggregation meliorate in alter for 1/8th Mile but again as the Slope uphill became steeper it STOPPED. SO NOW He thinks its the MAF Sensor.
We ran the OBD2 on this and the cipher threw Oxygen Sensor bad front one - one before cat coverter .I got a newborn O2 sensor but the mechanic said he could not place it on because the place was likewise diminutive to manipulate. So he tired but failed.
My Q 's are
<> crapper a FAILED O2 device drive the MAF Sensor to go nuts same this or the MAF itself has become MAD and needed to be changed
<> What added could be the difficulty here ..? any thoughts based on the symptoms.
Fuel Pump was a suspect EXCEPT for this incident - I put the automobile in R . It refused on an uphill. R on uphill . The Hood was unstoppered - and the journeyman did something to the MAF area Probably disconnected it or rehooked it and the Car got whatever humour and went R, upto like 1/8th knot and then stopped again.
Based on this could the F Pump be ruled discover ?
