Ram Van 2500.starter works but wont start
Blew the water pump, everything got soaked: alternator, coil etc. While driving with the
bad pump to get to the garage it would stall while depressing the gas pedal. Put in new
pump and now it wont start unless I jump it. Again, while it's running, depress the gas
quickly and it stalls.
I'd look at the High-voltage parts-----POWER to the coil or coil packs (you didn't say what year) if present check the coil, both ohms to ground from HOT and from secondary -compare them....ignition wires can leak to the atmosphere...in fact high resistance is what the high- voltage does best in...what I'm getting at is the high-tension wires should be replaced with reputable replacements...to save money could give 'em a shower with WD-40 (water displacer) pull a sparkplug, grab hold of the sparkplug with a jumper cable connected to the engine/chassis (ground) and have somebody turn the key and look for the presence of a spark...if spark is there would have to check fuel pressure and finally cam timing~
Do you have fuel pressure to the fuel rail (if a newer model) turn the key to the on position and listen for the fuel pump circulating through the fuel rail...on that rail is what looks like a tire filler valve (shroeder) could test the pressure there at the rail...perhaps the fuel pressure regulator has it's vacuum source cracked or fallen off and is issuing TOO much pressure to the injectors now~
Just how much of a meltdown did this engine suffer from? was there a shower of coolant under the hood?
