my friends dad has a 91 sedan, starts rite up in the morning, but when it sits for a a few hours it wont start back up for 15 to 30 minutes, anyone know what it could be??? he just had the dizzy and the fuel filter replaced, and said the mechanics mentioned something bout the coolant sensor, i personally think it needs to either change the fuel pump or maybe the batterys low??? please help...

 

please help.. coolant sensor might actually be the problem, talked to my friends dad.... he said the mechanics said that the coolant sensor might be giving off the wrong signal to the computer telling it that the car is too hot....if anyone has ran into this problem, please help me... dont have a job anymore so i got to mae some gas money...

 

What error code(s) is the ECU throwing?

 

not sure yet??? im at work and will be working on it as soon as i get off... by the way do you count the blinks on the ecu to find the code??

 

anyone??

 

Does it crank and not start or does it not crank at all? If the first is true than it might be your main relay. If the second part is true then it might be the ignition switch, battery, starter.

 

it cranks but no start...

 

Most likely your main relay. Have you replaced or repaired it before?

 

I have the same problem. The main relay. Since im not too into the electronics and soldering how much should i expect to pay for a repair like this?

 

It's really simple. If you don't know anybody who can resolder the joints for you, you can probably take it to a local electronic repair shop and they shouldn't charge you too much, maybe 5-10 bucks.

 

Some more info.

Yup. wait for the long pause and start counting. It may throw more than one code.

Edit to say that the main relay sounds likely to me as well.

 

thanks everyone, i took a look at the car last nite... my friends dad, re wired the radiator fan and now only turns on when you plug it to the cigarette lighter.... and the main relay is under the dash rite??

 

Yup, behind the coin tray. Kind of a b!tch to get at.
