I have a 95 chevy that wont start. Drove it to work and 12hrs later it would just turn over and not fire was running good and then no start. Tried a new pmd and nothing. Took it to the shop and was told it needed a new timing chain. Put it on the trailer and brought it home did the chain and nothing all timing mark lined up the same way it come apart. I think I'm going to start drinking over this truck. This is what I have done so far the truck has 498500km on it and pulls our 26ft 5th wheel. The truck has in order of replacement and all are new. Pmd $450 crank sensor $129 timing chain and gears,$278 injection pump $1899 remove all grounds and cleaned with sand paper and contact cleaner please help. Thank you for any help you give.

 

It would help to have more info as there are many ways that these trucks will not start please fill out and copy and paste this list and we will have a better idea of what is going on with your rig

ATF in the fuel is a bad idea it has friction agents in it and over time it will be like running sand paper thru the IP 2 stroke mix is what you should put in with your fuel to add lubricity a 1/2 ounce to 1 ounce per gallon of fuel and I myself am leaning towards a bad PMD mounted under the hood is a bad location due to heat soak

 

Thank you for the tip on the oil. The pmd are new I bought on and the other come with the pump and nether on has gotten any run time on it I tried all 3 the old one and new ones on a friends 97 and it start right now. Could the ignition switch do any thing. All in all I only have 2 things left the ignition switch and a pcm after all what's left to change.

 

have you got the known working PMD mounted to a heat sink ?? if so try cleanining the ground between the heat sink and where you have it mounted

 

It's grounded to the ip I'm using the ip harness its just bolted to top side of intake right now will get a cable and run it over to the air box later if I get it running cant put it in the bumper for the water and snow in alberta

 

It's a sealed unit unless you are submerged water wont hurt it but if you dont do the bumper relocate go low in the engine compartment as heat rises and heat is a PMD's worst enemy

 

No fuel from an injector line while cranking is PMD,IP or ECM-air in the lines or a plugged fuel filter could also be a cause for concern.

The water drain valve is unfiltered fuel so a plugged filter could still be a problem.
Does the fuel shut off solenoid work?

there have been times where the IP driv ley has sheared adn the IP doesn't turn with the timing gears-vry rare and usually from a seized IP but not always.
