89 d90 wont start

Hi and thanks in advance for any advice.

So symptoms prior to wont start were: dying at idle and then barely started then wouldn't start at all.
Checked fuel solenoid have 12 volts and clicks. (not super loud but audible)
The rockers are moving so I still have a belt.
Changed fuel filter. Has plenty of fuel pressure to IP
Cracked high pressure fittings at injectors and cranked it over. I have some fuel from IP but I'm not sure how much I should have. Steady drops but seems like it should be more???

What should I do next? I'm guessing the pump is shot out. I'll know if the belt hopped a link when I tear it down to pull the pump but am I missing something? I have a couple big Cats that shoot fuel everywhere when I bleed them but the pumps are enormous.

Also is there a way to bypass the shut off solenoid? Wasn't that impressed with the click.

Thanks, Bill

Maybe not a fuel problem?

This is a 2.5NA?? They can be a pain if any air gets in there.

First make sure the fuel solenoid is not the problem. Pull it off and remove the valve guts. Check for contamination in there. Put is back in with no valve guts. Crank it with the injector connectors cracks at full throttle. Then tighten and see how it goes. Never seen a pump die completely, so that is a doubtful cause.

????????

What Red90 meant was air in the fuel system.

It would be so nice when looking for help if you state which engine and any thing you have done, most of us D90 guys have balls that are made of meat not crystal.

Its an 89 2.5 tdi

I just finished following your directions on the shut off solenoid. No debris. took the plunger out and cranked it again. no luck. Wearing the battery down so putting it on the charger.

Seems like more fuel at the injector nuts though. Ill do them one at a time while cranking after the battery's back.

Do the glow plugs read 12v only when cranking? Is there a relay or timer for them?

Would appear the only electrical issue would be that solenoid? Theres nothing else to check really?

So next would be compression and timing right?

First we need to figure out if this is a 19J or a 200Tdi. Post up a picture for starters.
Second, who is having the problem, Bill or Steve? We have one to many cooks here in the kitchen.

Obviously not the same engine, but my '96 12V Cummins had the exact same issues last week. I changed the overflow valve on the back side of the IP, and it's like I have a new engine @ 252k. Not sure if a 19j has a similar setup but I would imagine so.
