1997 7.3
Before replacing Glow Pugs and new valve cover gasket truck would start and run. I did however wash the engine while it was running. Before I replaced the glow plugs for obvious reasons. This truck has 480,000 miles. It tries to start but just hits and smokes. I did buy the zd11 glow plugs. When I say smokes it smokes like a freight train while trying to start the truck. Any suggestions? Btw no codes , hooked up my snap on Modis edge.

Glow plug relay good?
What is the CCA of the batts and where are you located with the temp when cranking? My beat *** engine starts down to mid 20F (lowest been around here lately) without being plugged in to the wall.

thanks I will try that. I have hooked a test light to it already it stays on for about 2 min. Wouldn’t the scanner pick up if the sensors were bad?

Scanner will not tell you what a problem is, you must understand the data. Then test the sensor in question accordingly.

It could simply not be turning over fast enough if the starter is old.

Wahsing the engine always leads to trouble with sensors that have the seal compromised. Blow dry those sensors and anything electrical.

Maybe one of the wires is crushed between the vc and head. Check that out. Ohm the injectors and GP, .8-1.0 on the glow plugs and 3. something on the injectors just search on the stickies.

Smoking , injector tip broke off in cylinder
Replaced injector and injector cup. I was told that when a injector tip breaks off, it always puts a hole in the piston. Although I don’t have any fuel in the oil after I changed it.
When the injector tip broke off I had flames coming out of the exhaust and the o rings on the injector burnt off and that’s where all the fuel came from.
After the oil change and replacing the injector and injector cup I have no diesel in the oil.
My question is if the piston had a hole in it, wouldn’t diesel get in the oil?
Wouldn’t this be more of a head gasket being blown?
