K guys, i just bought a 95 maixma. (yes i still have the 2k2)

Ill post pics and info later, wanna get it running good first.

I need help, the car starts and will run for a few minutes, runs smooth too then starts to sputer and idle funny and then it dies (after about 5 minutes or so) and wont start back up untill it sits for about 30 minutes.


So far i checked the fuel filter and blew threw it, and its seemed good

Im thinking fuel pump?!??!?


What else can it be before I go out and spent the money on one....

 

Fuel injectors, fuel pressure regulator, MAF sensor, check that stuff too.

 

sounds like mass air flow

 

sounds like ects

 

I missplaced a fuel pump fuse last weekend, and it did just that. Start, idle real low and rough, then stops at a point. Gas pedal does nothing.

 

Do you have any CEL codes to go with these symptoms?

From what you posted, sounds like ECTS.

 

Wird thing is no cel, and when it does start and run for the first 5 minutes it runs perfect,


Whats ects, I noticed a relay for it, can some one give me more info?

How can i test

I also plan on hooking up a fuel pressure guage this weekend to test it, were would be the easiest hookup spot? at the fuel filter???

 

ECTS = Engine Coolant Temperature Sensor.

Does your gas pedal do anything to keep the engine going?

Looks like we might have a better explanation. Might be this also....

 

K ill replace the sesor, i think its cheap.


No its not the fuse i checked, it wouldnt run for as long as it does



-BTW i also get a weird clicking sound coming from somewhere after the car stalls?? almost sounds like a relay , its weird ??

Never heard this noise before inany of my maximas????


EDIT: when i hit the gas it sounds like its gona save the car for a qwk second but then just dies still....

 

The ECTS will set off a CEL though. I'm now leaning toward the FP.

 

FP ??

more info please..

 

fuel pressure. try getting a fuel pressure gauge and see if its reading properly.

 

Fuel Pump... also related to fuel pressure.

 

Put in a ects, no help.

I noticed the car stalls quicker now(after about 60 seconds), but it starts up each time and dies right after it reaches normal idl e(5 seconds or less).


I think its fuel related.

I wanna test the fuel pressure this weekend.

What should the psi be at ,and how can I test to see if its a bad fuel pump or if its just the regulater.

I noticed something major today


The car doesn't have a cell , but it wont let me scan using the odb tester , and it wont do self diagnostics when i turn the ecu screw!?!?!

Could this be a ECU problem??

 

HELP, car still starts but dies right away (maybe runs for 10 seconds) !!!

Tried another MAF, nothing changed....
Also tried a ecu from a 97 auto , nothing changed, car still stalls after each start up.

Changed the ECTS, no differance.


I also ordered a fuel pump today so ill see how that works out .


Any one have any other options?????


Also i just remeber my tester is ODB 2, but the car is a 95 , but i think the guy i got the car from said the ecu is from a 97 ??

Should I try using a odb 1?


HELP

 

My money is and has been on the fuel pump since post # 12.

 

I think you just need to clean your IACV and your TB. I think youll be set after that. Your IACV is probably getting stuck on start up, then fine once it warms up

-matt

 

Yes i changed the fuel filter.


And matty the car isnt fine when it warms up?

I think the problem got worse since the original post cause now it doesnt stay running for as long......

 

check the ground on your MAF sensor , look for post #17

 

Start with the cheapest fix, and work your way up to the more difficult/expensive.

Try mattys first, then move onto the MAF GND, then fuel pump.

 

dude ... i thought i was the only one with this problem...im sure urs is the same thing... it was the mass air flow sensor on the intake.. as soon as i changed mine it was running cool.... hey did ur car just die at intersections will in gear? mine sure did and it was pathetic... laters good luck

Louie

 

I tried using my friends MAF from his 96 and the car did the same exact thing.

I wish i could make it to a intersection, i cant make it outa my driveway.

thanks tho, im waiting on the fuel pump, if that dont fix it then ill prolly just sell the car or part it out??

 

if you are going to part it out, i'll buy the whole thing from you and fix it up.

 

Did you try mattys suggestions?

 

gona do that when I recieve the fuel pump, this way if cleaning it doesn't help im gona pop the fuel pump in right after.

Im pressed for time right now...lol

 

what readings did you get form the MAF sensor ground wire with engine at idle?
