Car will run on starter fulid I need help any one got any ideas

If the engine does not start within 5 seconds, the fuel pump automatically turns off, so it may be that the pump is actually working OK. If the engine starts with starter fluid, the ignition is probably OK, but there is a good chance that the injectors are not being fired. Check the injector fuses, and check that the PCM is actually trying to fire the injectors. NOID lamps would be a good way to test.

start checking and testing fuses and relays. fuel pump relay is under the driver side kick panel.

Any one got any ideas I tested all the wires from the ecm to the injectors they all have good wires I even tested the vat line going in to the ecm its sending the sig to turn fuel on even the fuel pump relay is get the power but it is not primeing or turning on and the injectors are still not fireing the ecm seems to be geting power and ground but not sure if the ecm is working or if there is something else I should check like is there something the send the injectors sig

If we assume the PCM is not fried, when every I do not have a pulse signal to the injectors the next thing I check after the fuse is to see if I have position signal to the PCM. If the PCM does not know the engine is turning then it will not fire the injectors.

I used a volt meter on the injectors and rlly just one of them and it did not seem to chage at all and the sig for the crank is going tho thats the frist thing I checked and im about 90% sure something caught on fire near the ecm looks like all the ac stuff is melted but the ecm looks on and theres no burn marks on it but in other words what I can see is the ecm is geting all it needs but is not sending out the sig to do so cuse my fuel pump is not primeing and the injectors arnt firing like I said before I traced all the wires back I looked for sig in less I reading them wrong but I can seem to find any thing and the pump dont kick on from oil pressure eather
