Cold start OK, no warm start without ether.

Help! This is my first post. I have a stock 1995 F350, 5 speed, just shy of 400,000 miles. My glow plug relay was just replaced. My CPS was just replaced. My fuel pump was replaced last July. One mechanic disconnected the fuel line from the pump and said it should be hitting the inside of my hood but was very weak when I cranked it. The fuel pressure at the schrader valve by the filter housing is 40psi. Now the problem. First start of the day, cycle the glow plugs and it starts. Turn it off and try to start it again before it gets cold and it just cranks. Shoot some starting fluid to it and it starts, reluctantly. My delivery guys set the air filter on fire the other day so I'm sure they would especially appreciate some help!

First off You came to the right place for help. You should never use starting fluid on a diesel engine, use WD-40 instead. The last thing you want is your engine to go boom. As far as the no start it could be a number of things. Can you scan it for codes? That would get you closer to identifying the issue. Plus this is a good bump for ya so some others can chime in.

you can use starting fluid as long as you use wd-40 at the same time and do not let your glow plugs cycle

see if any codes are in it first , make sure oil is full and in good shape

[strokethis69]

sounds like you are not getting enough fuel to start the engine,when you crank it does it shoot white smoke if it does not then you are not getting enough fuel to the cylinders

Will check for white smoke today. Have a mechanic who can read codes, will call him asap. Have tried WD-40, no go. Do you have to spray it while cranking? Once the truck is running it's fine. I go to LA weekly with a trailer and I have no trouble pulling the Grapevine so a fuel delivery problem is kind of weird. I either leave it idle or park on an incline, it starts with just a little roll. Thanks for the leads - will let you know the outcome. David.

I wonder if the hpop and injectors are worn to the point they will not build oil pressure high enough that the pcm is not turning on the fuel. With a shot of ether, the motor spins fast enough that the pcm turns on the IDM?

[DEESELDORF]

No smoke when cranking. Small puff of smoke when I use starting fluid. David

Just spoke to the mechanic who can read codes for me. He says that if there is no check engine light on there will be nothing to read, is this right? Help! I will be on the road to LA tonight and won't be back until tomorrow evening, if I don't break down. Thanks, David.
