    Can't do this cranking, no start, no codes, no rail pressure issues much longer.......

    Yes the plunger is there and everything is connected and installed properly. EVERYTHING I could possibly think of, I've checked and rechecked and rechecked and still to no avail have I gotten my fuel rail pressure to increase even a few psi. I have swapped out pumps with different spill valves...

    I'm at the point of saying I'm done....... I have completely rebuilt my motor, replaced high pressure fuel pump, place fuel rail, injectors, replaced every possible thing I can think of plus adding ground wires and what not. Cranking but not starting, fuel pressure not increasing, and only...

    Cx-7 turbo upgrade

    So no matter what since I changed turbos from stock to something a little bigger, I HAVE to tune my car? I'm really trying to clear up the whole confusion On- Is my car not starting because it needs retuned? I'm still new to the mechanic life and I've done far more than I've ever thought to even...

    Cx-7 turbo upgrade

    OK so definitely made sure I had all of my bolts in my intake manifold.... I am wondering what washer you are talking about between the block and the intake. I never knew there was a washer between the two. Is it something that is absolutely dire that needs replaced like my friction whashers on...

    Cx-7 turbo upgrade

    So I had a quick question due to my ignorance on the subject. If I upgrade my Turbo from my stock one, do I need to flash my ECU? I recently replaced my timing chain and VVT, Cam and crank position sensors, rebuilt my high pressure fuel pump, replaced injectors and fuel rail. I am beyond certain...

    Cx7 Cranks but no start. Replaced turbo and did timing.

    Fuel rail pressure relief valve has been replaced and still not getting pressure beyond, we will say 50psi as the median number and drops to 43 when cranking. So we have new turbo, new hpfp, relief valve, new crank and cam sensors, timing chain, vvt, tensioners, map sensor, battery, relays...

    Cx7 Cranks but no start. Replaced turbo and did timing.

    I mean the spill valve is part of the high pressure fuel pump is it not? I replaced the whole HPFP, splll valve and all. i am going to check my voltage with key on to my pump because it seems like its doing nothing or my rail isnt gaining any pressure like the relief valve is stuck open but if...

    Cx7 Cranks but no start. Replaced turbo and did timing.

    Ok I replaced the HPFP, and still only getting between 40-50 psi FRP. When trying to start the car it won't budge past 40-50psi either. What would be my next step because I am at a loss. TIMING was redone again to make sure I had it all lined up and everything was step by step done and I am...

    Cx7 Cranks but no start. Replaced turbo and did timing.

    Ok so went ahead and changed out my hpfp and housing, also changed the fuel rail and my psi went from a whole 8psi KOEO to 52 psi. Car still won't start and I have verified spark, fuel tho on the other hand.......could it possibly be the pressure sensor? How do you correctly test the pressure...

    Cx7 Cranks but no start. Replaced turbo and did timing.

    My exhaust cam was 180° out originally which was corrected, I'm going to remove my VC and make sure my cams are positioned same as in the link when engine is set at TDC. As mentioned my car started after the first go round but I messed up not replacing the washers on the crankshaft and my CAP...

    Cx7 Cranks but no start. Replaced turbo and did timing.

    So I'm new here and honestly kinda new to the mechanic life but I know a little more than someone with no knowledge at all. So I have a 2007 Mazda cx-7 Grand touring 2.3L and I got around amazingly for the last year, did my routine oil and maintenance, started having issues and long story short...
