codes 26, 83, and 87.... anything to do with the crank sensor??

[TL8apxrx7]

now my troubles are getting worse... motor still won't start and now its giving me three different codes...

26: mass air flow sensor or vane air flow sensor or transmission trmperature sensor fault

83: EGR solenoid circuit fault

87: fuel pump primary circuit fault

what is going on with my car?????

Hmmm.... what are you doing with a Gen 1 that has an EGR? is it a cali car?


if it isnt, you have some issues.



The first, i would guess because you have not been able to start the engine... that means it isnt warm so it cant read codes correctly? Or maybe you have a bad MAF... You have any other spares layin around?

The last could of been from a time you stalled the engine when starting from a stop. I dont think any of this would cause a no start issue... lead alone a crank sensor problem

 

[TL8apxrx7]

don't tell me that... I haven't even had this car 2 weeks yet... its only got 82k on it...

 

[Rockledge]

What year is the car? Which tranny? Put it in your signature.

she's a 1990 5 speed, a beautiful car if she would only run for me

Check for fuel pressure at the rails.

Do you hear the fuel pump prime when you first switch the key to the "on" position?

 

[TL8apxrx7]

I have fuel pressure and the pump does its thing when the key is switched on, I'm not getting any spark

 

[Rockledge]

None of the codes you listed has anything to do with spark.

If you want to check the ignition system, here you go:

FORD V6 DIS "NO START" PINPOINT TESTS

(The 3.8L SC and the SHO share the same exact DIS system...pin #s, wire colors, everything).

 

[TL8apxrx7]

I have no Idea how to do any of that...

No Spark = Bad CPS.

[Rockledge]

No Spark = Bad CPS.

Or a faulty DIS module, or maybe a bad ground somewhere.

Or a faulty DIS module, or maybe a bad ground somewhere.

There's a whole bunch of things that can cause a "no spark" condition. All of these, including the CPS, are on the list of possibles.

The diagnostic that Rockledge pointed to has the answers. If you don't have the techical knowledge or equipment to follow the diagnostic, you'll need to either find someone who can do it for you or you'll need to do the needed learning yourself.

Of course, you just start hanging parts on the engine and see if you get lucky.
