NO. You must have an ecm to run the injectors, as they require the proper drop ballast resistors that are in the ecm among other factors of proper fuel injector control that only the ecm can manage properly based on other sensor inputs for different driving conditions.

Gasoline will not dissolve the carbon deposits that clog the injectors but it will cause your engine to not start.

if you have engine oil in your fuel injectors then you have bigger problems then your car not starting..

This engine will have seven injectors. 6 are the running injectors and there is a "Cold Start" injector.

To start the Jag, is pretty simple... You have to prime the injectors... on the fuel rail is a treaded nipple, take the cap off and very slowly pour gas into the fuel rail... then the injectors are primed and the car should start... also check your fuel pump it should prime the injectors on its own...

I had a 1987 Chevy Celebrity that would start and then immediately die. It turned out to be bad fuel injectors. I replaced three fuel injectors and the problem has not returned.

check the fuses to the fuel pump and the fuses to the fuel injectors if you have injectors.

see my profile see link.

Depends on what you are looking for but I suggest you start a www. Yes they have tracker parts (JD)

Probably the fuel pump. Or the injectors.

If it starts in ANY gear, the neutral safety switch has most likely been bypassed.

The transponder is in the head of the key. The antennae for the transponder is the plastic ring around where the key is inserted. It can be bypassed by putting the head of the key under the cover of the column, next to the antennae. A normal mechanical key would then start the vehicle. Useful in remote start applications.

Have you replaced the fuel filter? Are you sure the pump is running and the fuse is not blown or the relay is bad. Do you have fire, and do you have fuel pressure to the injectors?

There are eight injectors, and possibly a ninth one, if it has a cold start injection system. there should be 1 per cylinder

Cleaning the fuel injectors is a good start.

that is the fuel pump building the pressure needed for the injectors to work

In a third gen, this would indicate that the neutral safety interlock (installed on the shifter, inside the console) is out of adjustment, is bypassed, or has failed.

Leaking fuel injectors may be causing the flooding.
