First off, check the wiring to the glowplugs and make sure all the plugs are connected and no bad wires. Check the HPOP (high pressure oil pump) resovior(sp.?) it should be full to about a half of an inch to the top. To check, simply remove the allen wrench plug from the top of the aluminum housing in the very front of your engine, if you cant find the plug, then remove the pressure sensor on the top of the LEFT side housing and stick a small screwdriver in the hole to check the level(should be half inch from top). If oil is not within half inch, then you might have LOW pressure oil pump problem.
If worried about your chip, simply unhook and reinstall all factory connections<<<<simple to do
, then see if it still has the problem in "stock". Also, try unhooking your EBS(engine backpressure sensor) on the front of the engine near the waterpump, then try to start, if this cures the problem then unhook the copper tube from the sensor to the manifold and clean out the carbon with VINEGAR, if this does not work, maybe then..........order a EBS stage 1 removal kit from dfuser
.com(35.00 shipped, and cheaper than a new EBS sensor):Thumbup:
I myself do not know much about a 7.3 but....my bro is walking me through this and if you have any more Q's, just ask, maybe we can help. You can PM me a phone# and we could walk you through this, we'll be home ALL weekend
, with not much to do.
This is a lot to check but it could save you some shop time cash:Thumbup: . Also, when re-connecting wiring check for corrosion, if present clean, and use di-electric grease when re-connecting. << This is found at most chain auto stores.
Hope this helps,
