Car was running well then stalled two days ago. Now it won't start.
It turns over at normal speed w/ ignition. Neither fuel pump gets power w/ignition. With fuel pump relay bypassed pumps deliver good volume of fuel to fuel injector rail. Car will not start with fuel pump relay bypassed. No spark at plugs. I'm stuck.
Well first the fuel pump relay is bad, that is easily replaced. next you have no spark. the first thing you do is take the cap off the distributerand crank the engine. if it spins that tell syou thyat at least the tang or gear on the shaft of the distributor is ok and not broken. next thing is remove the #1 plug and use a 1/4 drive extension 6" long and turn the crank by hand until the #1 cylinder is top dead center(put the extension in the hole of head where the plug was and you should feel the top of the piston also make sure you can feel the top of the piston with half the extension this way you don't drop it in the cylinder with the piston at TDC(top dead center) the rotor of the distributor should be pointed at the #1 firing position. IF it does not that means your timing is off and you need to retime it by taking off timing cover and either replacing the belt/chain or gears. now if you do not have a distributor and you have a coil pack there could be only 2 things that won't give spark. either a bad coil or your altenater is bad(the battery is responsible for starting not running the vehicle like alot of people assume. the altenator energizes the coil which inturngives spark. hope this helps you please rate this thanks
mine is a coil pack distributor,could the five pin fuel relay also be responsible for

The relay is $50 and I have replaced it once already. My manual has diagnostic for the relay and the relay passes. The diagnostic says there is likely an open to the ECU or bad ECU.
I checked my timing and it was correct.
I have been assuming that there is only one problem that causes the pumps not to get power and the sparks plugs not to fire. Afraid it may be the ECU, but would like to rule everything else out first.
CAR NOT RUNNING SMOOTH WITH
car turns over well its not getting any fuel in the trunk next to the hinge is a relay reset button is there anyway to bypass that just to get it home I have another car for parts thanks
volvo semi truck with is will not self check with ignition on and fuel pump not working
5.7 no fuel pump relay power from pcm no spark
very difficult to start at about 30 degrees celcius normal temperature . fuel pump relay showed a few socket legs were burnt.
turns over normally. fuel pump runs normal. 60 lbs of fuel pressure. has spark. does not fire.
ats light stays on when ignition turned on no fuel to injectors getting to pump ok
