replaced an engine mount at my buddys shop tonight and upon getting raer mount and engine all back in its normal position I try to start it and it just cranks over.
If given gas 1/10 attempts it will pop over and miss and not idle and run like complete garbage.

The car was 100% solid prior to removing the mount/reinstalling it.
I am throwing a Map code, as I am running a GM 3bar it still had not CEL prior and ran like a champ.
But now I get this Fuel supply code, this is where im stumped.
The fuel pump primes and I can smell fuel also (as i said it can get running rarly, but if pursuaded)
What causes the fuel supply system code 43?
and what would be the first place to start looking?
a bit of the heated o2 harness at the ecu is spliced. where do these connect after the ecu, Im also throwing that Ho2s code.

pull the spark plugs, if you smell gas they should be wet, if they arent gas probably isnt getting into the cylinder, work back from there.

 

im having the same problem no fuel is getting to my **** i checked the injectors nuthing check the furl rail nuthingi was getting fuel to the filter but now im not so i think its my pump i was wondering how to check the pump if the ecu is bad??? cause pior to checking for fuel i thought that my ecu wires may have come loose witch they did so i fixed it and now im not getting any fuel at all its just a wonder to me how one day your car is running and the next day you go to start it and it cranks but doesnt turn over

 

SLYFOX
1. check for 2 second prime when turning key to ON position. (listen for pump)
2. Reach under dash and feel for Mail relay(large White box right above hood release. held in with 10mm bolt), hold it while putting key to On position should click for fuel pump prime.
3. Check 15amp Ecu fuse underhood
4. Check Fuel pump fuse, srs, ign... ect just to be sure all else is good.


Now back to My problem, They are getting Fuel.
And I have continuity from each injector to the Injector Distributor block on the driver side shock tower.
Fuel pump primes, and as I said I can get it to run. It runs soo bad it wouldnt make it 2 feet. if gas is held constant it will just die out, even when gas is pinned to the floor it will die out.
Fuel pressure in the rail is at ~30psi, with 1000cc injectors.

 

Problem solved

being there is zero O2 feedback and Im running zero o2 sensors. It was getting all its info from the tune/map sensor and upon closer inspection one of the wires on the GM 3 bar was pulled a bit too far outta the connector.
although it didnt act like most failed map sensors it makes perfect sense.

 

Still wont idle, Fuel supply Code 41 still after disconnecting ecu.
Car runs very bad and falls on its face above 4 thousand rpm.

SRS Light is a constant.
