Help Please.. Maybe goodbye

[SHOOFF13]

I had someone take off my intake manifold to put on my bbb's and ported intake. Everything seems to be wrong with the car and nobody can figure out what the problem is. It's been to 2 mechanics shops and not 1 person can figure out what happened. The car would not get any type of spark at all, the mechanic told me it was the camshaft position sensor so I got that replaced and still the same problem is happening. There is no spark at all they're definitely thinking it's a problem within the wiring. My car is getting flatbedded on monday to a wire specialist that my mechanic knows if he can't figure out the problem, my beautiful sho that I have spent 4 yrs modifying and making it the best it could be will have to be either parted out or sold as is :cry: I really don't want to have to get rid of it considering the car has been my life since I got it and there is soo much money invested in it, but sometimes you need to do what you got to do. Please someone try to help me with this problem.

Thank you in advance for any help you may offer. It would be highly appreciated if I could get this problem figured out and solved and have my car running like it should. Any SHO specialists in the area who could come down to East Boston, MA and check it out? Let me know.

are the two bolts at the crossover tube (the end of the intake over the belts) in place? Also.....it could be the Crank Position Sensor. That would definitly cause a no spark situation.

 

[SHOOFF13]

Yes, the bolts are in place and that sensor was checked out to be fine. I don't know what else possible the problem could be.

 

[Devin]

This may be a stupid comment, but have you checked the coil pack?

 

[SHOtimer]

Yes, the bolts are in place and that sensor was checked out to be fine. I don't know what else possible the problem could be.

If all that happened was the intake being removed you probably have a problem with the DIS ground path. How was the crank sensor checked out to 'be fine'?

We had another sensor and put it in its place and the same problem happened. Like a trial and error situation. I was thinking of the dis also hopefully when the wire person checks everything out he will find out whats up.

 

[SHOOFF13]

I was thinking when he was trying to put the whole intake manifold back on he might have tugged off a ground or loosened 1 up. I will let everybody know what happens and what the problem is when it is checked out this monday. Hopefully everything will be ok and my sho will be back on the road soon.

yeah isnt there a ground on the manifold bracket tward the firewall on the passengers side? check to see if thats there... i think ive seen a car run without it once, but id check anyway

 

[ycode90]

Agreed check the intake ground the dis is sesitive and the ground would have been off to do the specified work.

It is hard to believe that your mechanic put in a new crank sensor based on your description since it's a several hour job. My guess is he swapped the CAM sensor which will NOT cause a "no spark" condition. Sounds like he's just been hanging parts on the car and seeing if he gets lucky.

rangerj and I have both posted extensively on troubleshooting no spark and CPS fault issues. Dig up these past posts using the Advanced SEARCH tool and you will be miles ahead.

That said, this is NOT a complicated ignition system. If you have the factory service procedure, it's painfully simple to follow to locate the source of a "no spark" condition.

If you don't have the factory procedure, downloads of the 92-up CDs are available from www.fordcds.com

The V6 SHO DIS and the 3.8L Super Coupe DIS are identical, right down to the wire colors. As such, you can use the pinpoint tests found here:

Is the ground strap hooked up?

Is your intake painted?

This is the factory procedure for the 89. It closely tracks the later year's procedures but is still spot on for diagnosing the no spark fault. Remembered to bookmark it this time...

Print it out and either have the mechanic follow it or do it yourself. It ain't rocket science.

This procedure will catch the common stuff, ie, ground path, coil supply voltage, CPS fault, etc pretty quickly.

Wanna bet someone painted or powdercoated his new intake?

You're going to sell your car because you cant get it to start? I'm guessing your DIS isn't grounded properly.

 

[SuperHO]

Give ya $500 for it.......

Seriously.....I'm in agreeance with everyone else.....crank sensor, coil pack or a bad ground somewheres. If someone else pulled your intake and didn't know what the **** they were doing, chances are the ground that goes from the back of the intake to the firewall is not hooked up and causing issues.


it would also appear the gentleman who's working on your car probably shouldn't be.

 

[DHMag]

if you disconnected the MAF and coil pack, perhaps the connector plugs were switched upon reinstall.

 

[1993MTXSHO]

Im goign to say ground as well, since the intake was taken off and the car ran fine beforehand (im assuming). Dont sell your car because of this. This may be a stupid question because im assuming eventually you would hear something fire, but are the plug wires on in the right order?

 

[SHOOFF13]

Everything should be back to normal as it came off the car in the first place. The only thing I'm thinking is maybe the painting of the intake manifold could have somethin to do with it. Maybe the grounds aren't the way they should be do to the paint. Could this be a possibility?

 

[Bizzy]

Absolutely.

Double check where the DIS connects to the crossover tube (only the bottom 2 screws are the grounds), the areas where the bolts that hold the crossover tube to the intake as well as the ground strap. The paint will make it difficult for those areas to get a good ground. Shave/scrape or otherwise remove the paint in those areas and you should be good to go.
