I have a 94 2500 6.5 turbo I've only had it about 8 weeks the other day while driving it shut off like it was out of fuel.

I read a lot about the pmds I looked all through the form and was convinced it was the pmd so i bought a brand new one installed it and still wouldn't start.

I'm not the type to just replace things till i find the problem but being i didn't know the history on the truck and read the form i was sure the pmd was it.

So after it still didn't start i read more and more i tested everything according to the form and couldn't find no problems.

So i was convinced it was the ip. i pulled it off and discovered i had a odd ball ip 5068.

So i send it to pensacola fuel injection and had it rebuilt got it back and installed it and it still wouldn't start.

Then i was sick and puzzled so i read more.

Oh i had the codes read before i started and it showed 13.

So i figured i was over looking something.

So i looked again and did more checks and couldn't find any thing.

So i replaced the crank sensor still nothing.

So a few people i talked to convinced me it was the ecm. they said that was all that was left. well i bought a rebuilt 1 installed it same thing want start so i lost.

Yes its got fuel i even added 10 gal before i replaced any thing to make sure that wasn't the problem.

Lift pump is working i even bypassed the op switch.

Still nothing it just spins and spins has plenty of compression and isn't making any strange noises.

I'm getting fuel to the ip but nothing out of it.

I checked the old pump before i removed it and the new pump no fuel coming out.

I checked return lines, there free flowing.

Do you guys think maybe the prom is bad because the new ecm didn't have a prom and i had to install mine?

I found where someone said the green wire going to the pmd should have 1.2vdc while cranking this is the signal wire.

Mine only has 0.4 while turning over i checked it at the connector and the ecm.

It didn't change what would be causing this and could this be my problem why there's no fuel comming out the ip?

Please guys i need help im out of cash and have no wheels.

Sorry for all questions do any of you have any suggestions of what it could be or any thing else to check?

Its had me puzzled for 3 weeks now. I'm gonna keep working on it but i don't know what else to do

I'll keep yall posted if i get her back going and also what the final issue ends up being if i find it

But for some reason the fuel solenoid isn't getting power I can't figure it out.

I've checked everything and damn near replaced everything there's something somewhere else besides the pmd that runs it.

I guess but I can't put my finger on it I've done about give up.

I don't know what else to do or check I just ordered a GM service manual off eBay, I hope it arrives quick.

I'm gonna go over every circuit till I find it.

But I'm still open for any suggestions I let you guys know what it ends up be if I find it.

Thanks for all the help guys
