92 mustang gt manual.
I need your guys help on this cause i can't figure it out. I had 351w head on my 302 and the valve seats started going bad. I upgraded the heads to the dart pro 1 heads and put a msd pro dizzy on the car..... only things I did to it. At first (after installing those things) the car would start up after a few turns of the key, don't know why, but it did start and ran good. After starting it 3 or 4 times, it just gave up and it wouldnt crank over. I replace the starter with a mini torque starter (for some reason my car had an older starter in it), it was acting like I had a dead battery and was cranking slowly.... not enough to start it. I take the spark plugs out and it cranks fine. Not sure what it could be. I have replaced the starter soleniod as well.


I wouldn't think the compression changed enough to have to get a high compression starter

Add a ground between the head and battery

Add a ground between the head and battery

Good advice. Hard to overestimate the value of solid grounding.

I don't see in your post where you checked your battery, but an old unit can give big headache's... Get it tested first.

Has a new battery as well

sounds like the oil pump shaft could have fallen out when you pulled the old distributor, or you just have it timed wrong.

But it ran a few times after the new parts were put on. Plus wouldn't that prevent me from putting the new distributor in?

Can you try the old distributor? Starting a few times and then not starting at all is a pretty strong indicator of an ignition part taking a dump. MSD distributors are notorious for being pieces of shit right out of the box for the past few years and I have read multiple stories of people on the corral with this exact same problem with MSD distributors. That is, they work fine a few times and then take a dump.

I can try that.

Bad ground/electrical would be my first guess as well - personal experience on that one. Bad starter would be my second. Bad distributor would be my third. I believe you said msd and there's tons of bad out of the box complaints on them online.

Not necessarily, I did something very similar on a 390 once. The shaft didn't fall all the way out, and didn't engage the bottom of the distributor either. it's been several years since this happened so details are a little fuzzy.

It's worth looking into before you start throwing money around on parts you don't need to replace.

I bought an MSD coil for my Bronco a few years ago and it shit the bed after only a couple of months. I had replaced it along with the wires and plugs, but fortunately kept the old coil. After troubleshooting for 2 days I finally swapped the old one back on and it fired right up.

Were the plugs wet with water when you pulled them out?
If you have a port mismatch, it will allow water to seep in.

Look here and GL..

Ok so here is an update... after getting a new starter and following some bad wires and replacing them, the car cranks, but now no spark.... sort of.... the starter makes a clicking noise while trying to crank and when it does it gets spark, but this is on and off clicking. I have checked the tfi harness and it's getting power, I checked the coil and it's getting power, checked my ignition box and it's getting power. There is a spark but not when it's cranking. I don't know what else to look at....
