engine won't start

[CSTAN]

my stock 93 dodge 4x4 stopped last february in -30 degree weather and i can't get it to start. i replaced water separator filter and lift pump. i also bled low and high pressure sides of air several times. i'm getting voltage to my solenoid on injection pump---used test light. i also gapped crank sensor to . 050 like dodge repair manual calls for... ... . still won't start. what gives?

need mare info to help other wize its a guess, so lets start guessing , in your post you mentioned air , so I that I'ld say that fuel lines or hoses are sucking air , I've read a lot of post that most yrs. have this problum, hoses going to tank ,the hoses get soft & porse , the metal lines where they have the welded hold downs can crack the trick is finding the leak, pressureizing the tank with 5-10lbs of air to check as far as the system will pass it , but first look for fuel pressure and that both the lift pump and fuel distributer are able to make pressure . use a small container with fuel and short hose and go direct to componants to go around the hoses and lines . that way you know both pumps are getting fuel and if they don'nt make pressure there's your problum.

I had a bus die on the road. I found the fuel filter housing (Racor) had rotted through (aluminum) and split at a pipe fitting. It was sucking air. I was able to narrow things down after I removed the suction line near the lift pump and operated the engine on fuel from a plastic container.

You may have voltage going to the fuel shutoff solenoid but that doesn't mean it is opening. Could be the coil in the thing is burned out. Remove the solenoid from the pump and carefully pull the spring and plunger out. Reinstall on the pump and truy to start. If it will start, the only way to kill the engine is with the lever on the side of the pump. At least there is a way to check it out.



As far as air in the lines - if there is no fuel getting to the engine, the engine will sound like it is turning over faster than usual. Could be air or could be a solenoid gone bad. I would check the solenoid out and see if that is the problem. If it is, great, all you gotta do is replace it. If that is not the problem then at least you know that is not the cause.

Geezzzz Scott... . what the heck would "rot" a filter housing like that... . short of running 90% corrosive or contaminated water thru it...

I ask cause I've got a one behind the seat and don't like the sound of your experience...

Bob,



Take a pill and chase it with (clean) #2



The filter is setting inside the frame rail, just behind the front tire. The tire throws dirt and road salt onto the housing. The salt attacks the aluminum and dun 'et a hole through the top of the casting. It weakened to the point that a boss where a pipe fitting is located cracked the aluminum and began pulling air.



The housing resembles a toy solilder that was melted down and then blown up with an M80. Salt = BAD
