Question about Cadillac DeVille

2 Answers

Hi, i recently had my transmission replaced on my 94 cadillac deville, and now my car will not crank. It had been sitting for about a year after it broke down. i chked to make sure the fuel pump is working properly, it was putting out about 38 lbs of pressure so i disconnected the fuel rail and cleaned it out with sme fuel injection/ carb spray. I removed and cleaned the injectors. and still nothing. i knw its getting spark because i sprayed starter fluid into the intake and the engine fired up but shut back off after a few seconds. someone tld me to chk the computer but is it possible for it to go bad just frm sitting with no battery?

It could be but i would say you may have injector problem, you have spark and fuel pressure and car starts if you spray starting fluid into it, i know it dies after burning out the starting fluid, this sounds like the injectors are not plusing, this can be cause by a bad connection or injectors or computer, check the wiring to injectors, a good test that would tell you right away if the injectors are bad or if the signal is not getting to them, this is with a noid light, this is a small light that connects to the injector plug of an injector and then try to start engine, if the light blinks then its getting power if it doesnt then it could be computer or wiring, if it blinks then the injectors are bad another thing to check first is the fuses there are fuses for the injectors check fuses first, good luck.

First check that all the battery connections are clean and tight, also check to see if it starts in neutral. Play with the gear shift lever,pulling up or down the neutral safety switch may be out of adjustment If you need more help get back to me. Thanks Ray

My 2003 cadillac deville dts drags when i try to crank it, I replaced the battery and starter, and it still wont crank.


Hi Able:
"Crank" to me means turn over.
"Fire" means actually try to run.
If it won't crank and you have a new battery and starter, I'd be checking the terminal connections, wires, cround connection, and solenoid. If all of those are good then we need to start checking the engine condition. Recently running or sitting for 5 years and full of rust?

I can't get my 1997 cadillac deville to start. It has been sitting for a couple of years with no activity


If it wont crank over the battery might be to weak to start the car but just have enoughf juice to run the electronics in the car.
Or the starter died.
1st charge the battery up and see if that works.
2nd if the fully charged battery dosent solve the problem then replace the starter.

Has the fuel pressure been tested? Have you ever replaced the MAF sensor in the air intake hose to the engine? DO you have a check engine light on?

94 Cadillac DeVille: Car would only run for 20


When the car has the crank/no start, at that point see which is missing. Test for fuel and spark. I think it has to do with fuel, a tired fuel pump or relay. But remember to check the oil sending unit. If it fails it will shut down the fuel system.
