Help!!!!

[brnxbmrfn]

i just picked up a 91 for $400 at an abandoned car auction. when i got it home i noticed a PROFUSE power steering leak. (1 quart every 2 days). i fixed that. it was a loose line out of the rack. HOORAY easy fix. i went to start the car after fixing the leak and and it was popping and sputtering and wouldnt fire off. i finally got it to start. once it started the tach wasnt working. it ran fine, no misfires or anything like that. i talked to a ford tech buddy of mine and he said the tach signal comes off the ckp. well i went ahead and bit the bullet and replaced the ckp. didnt fix it. i figured the next thing is the dis. went and got a new one. didnt fix it. however when you unplug the dis and crank... it cranks great. doesnt pop or anything. sounds like it normally should. i checked out a wiring diagram and the only thing left i can think of is cps or ecm. when i unplugged the cps there was no change in the way it cranked. another thing i noticed is when im cranking the car the tach will show about 300 rpms but once it starts it doesnt work. there is no check engine light. i dont know if there are any codes because i dont have a code reader and i dont know how to check them without one. any insight would be helpful. the next step for me is going to be to replace the cps.

thanks a million

Did you use a feeler gauge when installing the crank sensor?

 

[brnxbmrfn]

yes every install instruction ive looked at said to put it to .030" gap.

That's what it's supposed to be.

have you ever experienced this problem. if so what was the cause. i cant really afford to keep throwing parts at it. and i dont have the money to do a diagnosis in a shop. especially since the "s" in the SHO emblem looks like a $ to them.

To me it's weird that your tach works while cranking but when it's running it won't work at all. Aside from a wiring problem the last two things that I can think of is a bad cam sensor or PCM.

i'm gonna vote cam sensor on this one.

 

[shonuffmine]

X 2 on the cam sensor, or DIS mod is not grounded

 

[frosho]

It's the cam sensor. You Ford tech buddy was mistaken, the tach is run off the cam sensor not the crank sensor.

Lesson #1 Never bring a old SHO in a Ford dealer. the techs that worked on them back then are long gone (or dont remember anything about them).

The SHO is alone in its league , the only people you should trust is the people on the shoforum.

Oh but dont worry , alot of us did that mistake once - including me.

update to the problem...... the dis was grounded properly. and was still good. problem wasnt the pcm either. i went and got a $22 cam sensor took 15 mins and put it in. shes screamin again. thanks for the help. i am a new sho owner with alot to learn about these cars. but ill tell ya im in love with it already. the wife says... "whats your obsession with fords all of a sudden?" i said "not ford babe... SHO's"

well i have to tell you... there are some people on the shoforum who i shouldnt trust either. there are some people who dont know what they're talking about. not saying your one of them. just simply making a point.

Yup you got that right , You help you figure out who's telling the truth or close to it , usually with the join date , the reputation and the post counts should help you decide who's on the right track. Not 100% accuracy , but it should be heavier in the balance then some newb that just came in.
