Fuel pump relay not pulling in if I jump it out fuel pumps will run, if I spray gasoline into intake engine runs fine seems like I'm not getting any injector pulse what part would give the PCM the input to allow injector pulse any help appreciated thank you

First one ime it will start next 5 times wont, if dump gas in throtle body fires up. Injectors not kicking in. New fuel pump actually from tank forward all new. What happening?
Secound 4x4 will no engage no light or anything. Went tbrew fuses replaced silinod on firewall went threw relays, could this be motor on transfer case?

My car won't start but there is no error code provided, injectors are clean, ECM signal is negative and there is spark in every spark plug. What else should I check?

It started with jerks while driving; when starting gold y vibrates and then it normalizes. While driving it losed power as if choking a little, but now it got worse. It chokes while accelerating and sounds as if exploding, when I let go it keeps driving; if I accelerate again it does the same but it doesn't stall. If I turn it off for 5 seconds it works for 10 minutes and then it fails again. I alreadi cleaned the injectors, changed spark plugs, air filter, fuel filter, fuel pump, coils and their sensors. I've already had this problem for a year and they can't solve it, yesterday I scanned it and had air sensor error, but changing it didn't fix it.

Ignition busted key fob lost fob reader gone no power to injectors no power to fuel pump. Anti theft system needs b bypass

Hello! I just bought a carbureted V8 Ford F150, but the problem I have is that it lacks acceleration and the engine vibrates the same as if the injectors were clogged, but obviously it is carbureted. What I haven't checked is the timing with spark plugs and cables. It was already without use for over 3 years, and to add more information it doesn't produce smoke or makes weird noises, and when it is in parking and you throttle the engine it sounds as if something was uneven.

Replace the fuel pump fuel filter fuel lines injectors spark plugs spark plug wires to coil EGR map crankshaft position sensor fuel regulator sensor and still nothing

Anytime the truck is running i get the strong odor of fuel. I have inspected the entire fuel system from tank to injectors and can not locate any leaks

I have changed the coil-packs, wires, plugs, egr value, & sensor. I have cleaned the injectors on #1 & #2 changed them around. After doing all this I'm not getting any fire in #2 and the above symptoms
I don't know what else to do.

Truck cranks but no start I replaced the fuel pump the fuel lines check the fuses are replaced the spark plugs spark plug coils or ignition coil spark plug wires EGR valve map sensors injectors ignition coil crankshaft positioning sensor and still no start it starts when you put starting fluid in it but dies right away now the fuel pump won't work

Unplug each fuel injector on driver side and there’s no difference in the way it’s running. Ran for 5 minutes get under and the exhaust is warm but not like the passenger side. I could touch the driver side without a burn on my hand. Not thinking about touching the passenger side. So that’s telling me there is no fuel to that fuel rail... the fuel comes in on the driver side and loops around to the passanger… so is this a ecu issue not telling the fuel injectors to fire? Or am I missing something here? I keep seeing online it could possibly be the cam phasers but I think the fuel would still be sprayed out the injector and at least burn in the exhaust and heat up the exhaust pipe, right? It started out of nowhere as a cylinder 5 missfire, then 5 snd 7. And now 5,6,7,8…

Got a truck from the oldest man on earth, 63k, replaced fuel tank, pump, filter, relay, pressure regulator, and injectors, also plugs and wires and battery, map sensor, throttle position sensor, and it still only starts on ether and won't stay running unless I'm putting ether in.

Lost key it in the teift mode and shut down fule pump and injectors . How can I bypass system without anything or any money

Can't seem to get rid of what is like a miss spitting and sputtering no power just changed coil pks they were aftermarket, along with injectors
Checked all the vacuum lines getting po1701 and 1704 codes and can't find or where to narrow it down

Okay the truck doesn't want to run right it's like it's got no power you can feel it misfire your kick in and off I've got a new ECM I got a new injectors I got a new coil packs I got a new tank I got a new fuel pressure regulator I got a new fuel pump I've got new coil packs new spark plugs cam sensor crank sensor the differential pressure feedback sensor throttle body positioner sensor all this has all been put in here pretty much all new stuff even replace the wiring harness from the ECM out to the engine plug and play can't figure out why it doesn't want to run down the road very good it'll be fine unless it's an electrical issue

Started with fuel issues. I've replace the pump and filter new injectors fuses relays plugs and wires...

Clicking fuel relay
Clicking noise behind motor
Overdrive off light not turning off
Theft light won't turn off

Still crank no start situation

The truck will crank but has no power to coil ignition module or fuel shutoff switch (inertial) we hav jumped between 2 and 6 in the eec connector and still no power to switch checked main ignition switch and all wires have power in the run position found a bad wire to main fuse panel under hood to the # 22 fuse repaired and restored power. Had ignition mod. Tested used noid light on injectors verified spark replaced all 6 injectors verified base timing and plug wire location HAVE Questions about noid light test seems the light is blinking way to fast when cranking like its seeing every cylinder pulse signal not just the one I am connected to ???
