Has anyone ever ran into the same problem as me where the car was idling for 10mins and shut off and never started again . I’m currently receiving no spark . I am getting fuel . My compression is 110 on each cylinder. Changed the camshaft and crankshaft sensor. Sent my DME to ECUPRO and they started it up on their motor with no problem according to what they told me. Changed the engine wiring harness and fuse box . Changed the power wire that runs from the truck to the front of the car. Im getting 12v at the coil pack power wire and I’m getting 12v at the signal wires. The car cranks only doesn’t sound like it wants to turn over. Also no codes are popping up in the DME I have no check engine light

Did you scan it using INPA? My ELM ODB does not show everything that INPA shows when doing a fault scan

Have you tried a new or known good coil pack? Pull a spark plug, attach the plug wire to it, ground the side of the plug and have someone try to start the car. Are you getting spark? If not, the coil pack is bad.

Yeah, that would be my first guess if you have power at the coilpack...

yes I did scan it with INPA and there aren’t any current faults

Check the red wire from the coil connector.With ignition On must get plus 12V on pin nr.2
If is OK ,check the wiring between Ingnition coil connector and ECU.
Pin 1 from coil to pin A3 from ECU big connector
Pin 3 from coil to pin A4

I tested all of that and everything checked back ok . Could it be a timing issue maybe the car jumped timing idk . Cause all it’s doing is cranking I get 12v at the red wire and I get 12v at each signal wire for the coilpack when I turn the key

Yeah... if the timing is off enough, the car won't start. The triggers for the cam and crank will be nowhere near where they should be, but usually, it codes. I can only speak for Toyota, but if you mess the timing from one tooth, the car will start and run like crap, but code about cams being too retarded or advanced.

110 pounds of compression on each cylinder seem a little low to me....my cars are up around 180 or so.

I'm thinking maybe the timing chain has jumped a tooth or two.....the only way to really tell is to pull the front cover off and see if the chain marks are aligned or not. This is assuming that all the other parts that you have put on the car are good.....just because part is new, doesn't mean it a good working part
