Hello so I’m having problems with my g35, I have switch out my cam and crank shaft sensor and I change out my starter and fuel pump I changed out my fuel injectors and fuel rail and I changed out my spark plugs. & nothing I also changed out my ipdm and nothing I don’t know what else to do! Please help me!

 

Is it throwing codes you can check with OBD?

 

Just p0102 and I did have one for the throttle body but not anymore.

 

why am I having the same issue as you bro this sucksss, I literally did everything you did already

 

if you ever find the problem man shoot me a holler, but if I find the issue ima shoot you a holler

 

i will but at the moment I spent so much money I have to wait for awhile lol. It was running good and out of no where didn’t wanted to crank anymore so I changed out the battery and nothing I changed out the starter and nothing and than I thought It was a fuel problem I changed out the fuel pump and nothing and than I changed out the fuel injectors and fuel rail I change out the spark plugs and nothing I thought it was the ipdm and nothing I’m so done with it at this moment! I really need help! Each time I spray the starting fluid in the throttle it runs for like 10 secs and slowly just stops

 

bro if it starts for 10 secs and dies you’ll have to head into the fuel category most definitely. Because you definitely have spark . Like in my situation I sprayed in it and it doesn’t turn on so I have an electrical or spark problem. Check your whole fuel system, hook a fuel pressure gauge to it and see if that’s the culprit.

 

If you take the fuel bezel off does fuel come spraying out? When you take a spark plug out is it wet and reeks of fuel?

 

what fuel bezel? & no it wasn’t recking like fuel tho

 

that thing? Take the 2 10mm off and gently pull off cover your face and everything but see if fuel come out aggressively if it doesn’t you have a pressure issue. Be very detailed about how the fuel came out when you reply, also you mentioned the spark plugs aren’t wet, that totally heads into fuel pressure.

 

I did take it off! & it does have fuel!

 

did it feel pressurized if so how much? if anything the injectors are probably not firing, crank the vehicle real quick and pull a plug to see if it’s wet again

 

Z1 Motorsports sells a sandwich adapter you can put under that fuel damper which allows you to hook up a fuel pressure gauge.

 

Also, if you're throwing P0102 you have a MAF issue. I'd replace it with a Hitachi one because a bad MAF can cause a fail to start (not fail to crank).

EDIT: Or just unplug the MAF and see if the engine starts.

 

So I just realized there is no fuel pressure what should I do?
