I’m totally lost on this car I have spark no fuel I’ve replaced the crank sensor cam sensor the fuel pump the fuel injectors the harness is good I’ve checked the continuity from the sensors to the computer I’ve even purchased a new computer twice had it flashed and programmed and the car would start and run 3-4 times then something is burning up the computer best I can explain and it’s same senerio all over again the ignition switch has power it’s sending signal even mechanic has given up on this car and at $79 hour I don’t have the money to take it around to others to guess and not fix it the fuel pump does work it feeds to the fuel rails have power to injectors just no pulse when turned over
Ok thank you I will try this I will clean the intake and I have already repaired the leak
Yesterday after repair the leak the
Calc load went to 25.1 %
And the STFT B1 went to -15.6 %
A difference but not a lotOk I driove it last night I turned the car over about 10 times it finally started no codes I let it idle about 15 minutes, then I drove it about 3 miles then back home power seemed fine pulled it back into the garage and shut it off same thing but offer turning the engine over many times it does seem to run
I unhooked the fuel pressure line and hooked a hose to it and when the pump come on I do have fuel this is to the line running to the injectors I also checked the spark and did have spark but still no start condition
As far as I know the fuel pressure regulator is built into the fuel pump which I’ve already replaced so is the fuel filter
If this may help it is last readings of code reader just purchased it battery was dead so no codes I could not read before now due to reset this was all LD while it was running
Fuel sys 1 (CL)
Fuel sys 2 (NA)
Calc load (28.2%)
ECT (180 degrees F)
STFT B1 (-18.0%)
LTFT B1 (0.0%)
ENG RPM (800)
Veh speed (0 mph)
Spark Adv (12.0 degrees)
IAT (84 deg F)
MAF (0.60 lb/min)
TPS (0.8%)
02S Loc (02S11 and 02S12)
02S B1S1 (0.285 v)
STFT B1S1 (-18.0%)
02S B1S2 (0.300 v)
STFT B1S2 (99.2%)
OBDSup (OBDII)I currently have no way to test the fuel pressure, and what do you mean by vaccume where the MAF is the line that runs from the air intake to the engine is damaged but did not think this would cause a no start issue.
Also the port where you test the fuel pressure I removed the cap and there is a valve like a tire valve stem I pressed it with a screw driver no hiss of air, nor did any fuel come out, but the fuel pump is working I hear it pumping and also un clipped the hose at the pump had pressure in the line. Not sure if this is useful information.
