What causes a car to have no power to injectors?
No power to the fuel injectors can be caused by a few things. If the relays, fuses, and computer all check out then I would move on to looking at the engine management and fuel system.
Why is my 1.4 TDCi engine not firing?
The 1.4 TDCi engine also known as 1.4 HDi. The engine turns fine with no weird noises when cranking and no smoke is coming out. and after someone suggested that the fault could be the lack of fuel pressure in the rail so the ECU won’t fire the injectors (which turned out to be right).
What to do if your fuel pump won’t start?
Use a circuit tester to check all the electrical connections to the fuel pump. Turn the key to ON. If you see a current, then it is not the pump. If there is no current, check the fuse.
Is there 12 V on the injector plug?
Here’s what I’ve tested so far: tested the injector plug with light bulb and a multimeter during the ignition and startup but there is no 12 V on them (the black wire has no voltage in reference to plus or minus side of battery and the red wire has 1.2 V in reference to ground)

Why does my car engine not want to start?
If the engine still doesn’t seem like it wants to start, probably fuel is getting into the cylinders and your problems lies somewhere else. However, if the engine runs momentarily and dies, then the problem is that fuel is not getting to the cylinders. Check for a clogged fuel filter, or a bad fuel pressure regulator.

What should I do if my fitech car won’t start?
Process for startup. Turn on master power. Dual batteries which are charged. Also usually connected to a running car to keep voltage around 13 to ensure proper voltage. Turn on switch fuse panel power. Turn on fuel pump so pressure builds for prime shot. Wait for prime shot. Hit starter. If prime shot is wet, immediately fires all temps.
What should I do if my Ford fuel injector fails?
Fuel Injector Inspection – You can take the injectors out of your Ford and inspect them for damage, dirt or rust. You can start by removing the fuel rails and detaching each injector from the rail. When you remove the injector, there will be fuel that spills out of the rail, so make sure you do not get it on you or the ground.

What causes a fuel injector to get clogged?
Dirty Fuel Injectors – Residual fuel additive that is not dispensed within the manifold can leave a film on the fuel injectors. It can become a crusty coating on the injectors because of the heat within the engine. This residue can clog the injectors, impeding the spray. Clogged Fuel Injectors – Many things can clog up the fuel injectors.
