What Exactly is it and what does it do.

Backstory, Car doesnt start right away and my dad said it the timing might need advanced.

 

details dude, does take longer to crank or what?

 

Details needed. DIS, no distributor- timing control is in the hands of the ECU, nothing to adjust.

 

If it takes longer to crank with a warm engine, then it's the ECTS (Electronic Coolant Temperature Senosr)

 

Or MAF voltage.

 

Please specify exactly what happens that is problematic and when does it happen.

 

Timing may have skipped a tooth, but that would only happen if you've done some major work on it recently. i.e replace water pump, timing chain/sprockets etc.

 

There are MANY potential reasons for hard starts. We need more info vehicle maintenance history, mileage, more detailed description of when it happens, etc.

 

Sorry bout the long *** wait.

175xxx Miles
I've changed everything under sun
Including 2 Camshaft position sensors, crank shaft sensors
Fuel filter, starter, PCV valve, Air Filter.

 

And it only happens when warm, Probably going to chage fuel pump this weekend.

 

I wouldn't suspect the fuel pump just yet. Is the CEL(check engine light) on or been on? Have you gotten any codes? Has there been any stalling or hesitation? And odd as this may sound; Does your radiator fan act normally, or does it start early/stay on a long time/not turn on?

the radiator Is new, both fan are also new, and run when they are supposed to, the was stallin and hesitation at the begining before the fuel filter change, after that it has dispappeared.

 

i think you need to stop throwing parts at it and just have a sit down and think about what exactly are your problems and what are your most likely problems down to the rare rare problems. seems like you went with the cheaper parts first but think before you act to possible save you money

you timing probaly is the least likely thing

 

Like someone else mentioned, a bad engine coolant temp sensor (ECTS) can cause this.

 

Ok, just wondering, since I'm fighting a similar problem which is currently presenting itself as the Engine Coolant Temp Sensor(ECT(S)). Stalls/dies (or tries to) when mostly warmed up in my case. Last night it even gave a hard time starting after it had been driven a bit. Between the symtoms(which seem common to quite a few causes), and that the fan would sometimes start up WAY early, I went after the ECT. I pulled the old one and it checked marginal for air/room temp and ok for warm(~120*F), but for hot it freaked(jumped around until it finally just read open). As this has been an intermittent problem I won't know if that was the true cause for a while, but for you it's something to look at.

You didn't mention anything about the CEL/codes...any indications?

yeah, i recently changed my ECTS. I used to need to crank a while longer if the car sat for like 30 mins-1hr after being driven. Now it starts up like that! (snaps fingers) But the fans DO come on much more/earlier than usual.
