Sorry for this being so long. About 2 weeks ago my van just started cutting off while driving, could usually get it started back up but then when I got home I couldn't get it statyed, just turned over. I installed a new fuel pump, fuel filter including the two in the tank, CPS and the senser that screws in the head on the drivers side right behind the a/c compressor sorry forgot the name of it along with changed the oil and filter. It starts now but when you give it some gas and runs like crap. I had a remanufactured motor installed a while back and it now has about 60,000 on it. I have always had to plug it in even when around 45 degrees so while I already had things taken apart I checked the glow plug and AIH relays, was told the one towards the back is the glow plug relay. I replaced them because they looked old and I got the same draw on the hot side as the battery 12.2 but when I went to the other side and turned the key on I got nothing. Normally I would take it to a shop but in Huntingtown Md. we are not known for having honest and reliable shops or dealership. I would greatly appreciate and help. PS: by the way the service engine light stays on now.
