I have an 87 mustang that cranks normally but won't fire...i replaced the TFI module, checked all the wires, replaced the coil and still no start.
Can anyone help or have any idea what could be the problem?

 

You're sure you aren't getting any spark?

 

im getting spark i tested it with the spark tester tool...but no start

 

Maybe a fuel pump?

 

Hmm, from the list of replaced items it sounded like you weren't getting spark. However if you have spark there's only two other things to try. Check for fuel and check for compression. If either is missing ti won't start. My guess is fuel though....

 

i checked at the shrouder valve...when starting it sprays out fuel so fuel pump is ok.

 

At anytime did you mess with the timing? If you are getting spark and fuel the firing order might be a little off. I'd try there. Good Luck :biggrin:

 

I found a broken distributor rotor once to cause a no start...

just going where the post isn't

 

the distributor rotor is ok....but im thinking of replacing the distributor

 

i checked firing order and its ok
