Car Wont Start!!!! :(
 

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

Did you take the distributor out at all?? It's possible to have it 180 degrees out of phase, so it shows up as if the timing is correct when in fact it isn't. Happened to me last year during an engine change. Car had spark, but wouldn't start until I turned it over a full cycle and reset the timing. That would only happen though if you had your distributor right out of the car and were screwing around with it. Other thing I ran into with my distributor was when the magnetic pickup failed. Weird, intermittent spark interruption.

I did take out the distributor... but how do i reset it or turn it over a full cycle?

Well you have to start from scratch. Bring #1 piston to TDC, take your distributor and aim the rotor at the #1 on the cap, and drop it in. You might have to play with it a little, but she will go in. After that get a timing gun and set the timing at what you want.

If it still dont fire pull the distributor up enough to turn the rotor, and turn it 180 degrees, then drop it back in. That should do it. Good luck :tup

YEAAHHHHHHH!!! lol :chacha: It started thanks alot guys. If it weren't for your help, i would have had to overpay a mechanic to take a look at it.
Once again thank you to everyone who gave input!!

i kicked my fuse box once, and the car started :)

:tup lol nice...

Awesome! Glad it worked out.
