A bad CPS will prevent both fuel and spark - when the ECU doesn't get a valid signal from the CPS indicating that the engine is rotating, then it will shut off both fuel and spark. It sounds like you have solved the fuel delivery problem, but maybe not spark. If the engine rotates and does not fire, then it's a problem with either fuel deliver or spark. Disconnecting the dead battery's negative lead, taking it out of circuit may help. Even if you try jumping it off or charging it, the battery could have dead cell causing it to act like a giant resistor and "suck" all the jump-battery's extra power away. So does your engine rotate when you turn the key? If not, then I would look to the vehicle battery. Firing is when fuel is combusted by spark and the engine then continues to run after the start motor stops. Rotation is when the starter motor runs and the engine is rotating. I'm a bit confused by the terminology "It cranks like it wants too but doesn't actually turn over" and "There is no ticking or anything when we try to start." Let's use the terms "rotate" and "fire". There is no ticking or anything when we try to start. Tried jumping the battery even though it said it's giving full power. Rear SAM came out of same model so I didn't think it needed reset or whatever it's called. All the wires in the fuel system were checked and are powering what they need too (fuel sending unit etc) It had spark before replacing the rear SAM. We don't seem to be getting spark now but our tester isn't the most reliable. The fuel pump kicks on now, great fuel pressure at the rail. We replaced the Crankshaft position sensor, still didn't start.Ĭouldn't hear fuel pump so yanked that bad boy out and tested it, it worked.įound that the rear SAM was fried. It cranks like it wants too but doesn't actually turn over. ![]() I superviseĬar drove great, came home parked it went back out and it wouldn't start. Also, my boyfriend is the one working on the car since I'm 9 months pregnant. ![]() Then there's a little trick to getting the steering column out of the way.I'm new to this forum so I hope I posted in the right area. If you decide to DIY you need long socket extentions, to reach the bolts on the starter, since you have to fish the socket wrench in from the back of the tranny. Not sure on 2003, but on 2002 starter is on the back of the engine between firewall and engine, fish pipe carefully down to not damage hoses, lift and tap till it fires up. Keep the rod/pipe in the car in case it fails to fire until you get around to R&R'ing the starter. I cleaned it, and took it to an auto electric shop had the brushes replaced for $25 and put it back.īanging on it, helps to get it to make contact just long enough to get it turn over. So much so it prevented the brushes from making contact. I pulled my starter, and it was packed full of all the stuff left over from the brushes wearing down. I still would clean the battery terminals and try it just for shits and giggles. Next time you hear the click, tap the top of the starter with a piece of pipe like 3', or metal rod of some type.
