Help? Won't run!

So, I just did my 5 lug swap on the front (I know that didn't have anything to do with it). But when I got it off the jack stands, it'll crank but it dies when I let the clutch out sometimes even with the clutch still engaged. It cranks, but won't run. Don't know what the problem is. It'll run sometimes when I'm pulling the steering wheel towards me, but only sometimes. Thanks.

Check your basics first. You getting fuel pressure?

The big three are fuel,spark and air start with whatever is easiest for you but it sounds like a fuel issue

It runs if i stay on the gas, as soon as I let off it dies. I hear the fuel pump, and the relay but as far as pressure at the regulator I don't know. How would I check?

There is a schrader valve on your fuel rail to hook up a gauge and check fuel pressure I don't know the spec but you can look it up its an easy process to do

Ok, so I have fuel. I started it up and it died, so after that I started it up again and held the gas down to keep it running. I took it down the road and back about a half mile when I got back it idled perfectly. So, what now?

Do you have any aftermarket parts that have to do with fuel or spark

Negative, just your basic preventative maintenance. New fuel pump, relay, still has stock ignition except plugs, wires.

If your getting good fuel pressure and spark either you have a issue with getting air like the MAF or throttle body sounds like its an intermittent issue those are hard to track

Ok, how do I try to come at this then? I have never had a problem like this, everything has always been simple for the most part.

I would start simple.... You know you have spark and fuel... It always starts but will die sometimes after idle. I would clean the MAF sensor and check TPS voltage. Could be the TPS sensor going bad.

Ok, thanks. I'll clean my MAF, and check my TPS voltage today and see how that is. May not be able to get to it today though.

I have a quick question. How do you go about checking the TPS voltage?

I had a similar problem on my old fairmont, it would die at lights but would fire right back up until finally it would crank forever and wouldn't start. It ended up being the ignition control module for me.

You use a voltmeter, the voltage should be set to .98-.99

I can't remember which for sure, but if you test it with the voltmeter, one is ground one should show 4 volts and the other will show your voltage when key is turned on. Loosen the two screws slightly and rotate to adjust of needed and don't forget to retest.

The wire colors vary between year models, with the throttle closed it should be between .98 and 1 volt. Then you can test the sensor by opening your throttle and should see a steady increase to wide open throttle to roughly 4 volts. If your voltage suddenly drops off while opening, you more than likely have a bad TPS.

Got it, I feel like an idiot! Went to check my TPS, bumped my CAI pipe and it fell out of the sleeve to the throttle body. Snugged everything back up. Busted right off.....lol. The simple stuff right.

Here soon I'm gonna be undertaking a gt40p head and explorer intake swap on my 86, as well as doing the mass air conversion with cold air intake, bigger TB and EGR. So I'm sure you'll see plenty of tech questions from me posted soon, lol.

Lol, I'll do what I can to help. I'm about to jump into a GT40 head/intake with a TFS cam on mine with a bigger TB, etc. with a little something extra around 8 lbs or so...

Nice! In my opinion there's only one option for a power adder, and that's forced induction!
