Not much info to go on but, do a fuel pressure test to se if you are getting the proper fuel pressure to the injectors. Year, make, model and engine size would help us help you.
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?
Check compression.
the ignition module or injector fuse
unplug it and disconnect battery for a minute. plug in after battery reconnected
Have you checked the coil's ?
New one may be defective.
Get a new starter. It's gone bad and is trying to draw too much power and can cause a fire.
spark plug or injectors. Try cleaning injectors or replace plugs if that doesnt work try new ignitions wires maybe there is a melted or cut wire. happened to mine....
try plugs and wires that could be an issue and what wont it do?Does it turn over???
if you have a new coil then it is probally going to be the ignition module located on the distributor.
It wont shrink
It's impotence and not power isn't it?
