I have a 1999 B2500 which wont start.

When it turns over it seems to have a skipping motion. I first thought a timing belt or it skipped time. I check the marks and all seem good.

My next though is a crank position sensor, but its a b*** to get to. I am currently trying to find a wiring diagram to check for voltage.

It doesnt seem to be a fuel filter or fuel related. The fuel rail has pressure.

I am not getting any codes.

 

ok, I checked the crank sensor and it ohm'd out correctly and getting voltage out put.

I dont see a cam sensor yet, maybe not one on the engine?

I still dont have any codes. this seems strange.

I also check for voltage to the coil pack and its good. I havnt worked on many engines with two plugs per cylinder, but maybe a coild pack. I would think it would give me a code.

 

Well I tried the cam shaft sensor and no change. Appartmently it only should be putting out .1 volts ac.

I checked and made sure the EGR is closed during start.

Next going to check timing. If I can fugure this out. I really wish I had a manual.

 

I am having trouble with mine starting, but only off and on. It starts and runs well, then out of the blue it just won't start. After waiting a while 15-30 minutes, it will usually start again. I can't even think of what could be causing it. It's more pronounced when it's hot out. Anyone have any ideas what to look at? It is a 2000, standard . Any help would be appreciated. 2.5 ltr I think.

 

how old are the plugs and wires?

 

Hi I have a simaler problem I have a b2500 2.5 tai on a 05 plate I've changed filters fuel line injectorpump it ran fine for two weeks and now won't start any ideas ?

 

Mine ended up being a blown head gasket. The gasket was a total failure between 1-2-3 cylinders. Never blew into the coolant or oil so we didnt notice while running at all. Just wasnt ever able to get commpression again. Good luck.

 

Could it be a bad solenoid? Mine quit while running.tries to restart ,but won't. At first thought it jumped time...now thinking check solenoid 1st..process of elimination. Easier. ???

 

Last post in this thread was over 10 years ago......they have likely fixed or sold the truck.

Welcome to the forum though.

 

it will be fuel filter for sure
