great 1 down 2 to go
spark , makes sure spark fires on all 4 cyl.
timing light to #1 wire HV lead (front)see it flash fire at 0 mark? or near hood sticker spec.
then move light to #3 it now flashes at 6pm on pulley , no marks, there but lands there. (180deg)
then move light to #4 it now flashes at 0 on pulley , same 0 marks as #1 firing.
then move light to #2 it now flashes at 6pm on pulley , no marks there but lands there.
it must start, or at the worst case starts with 5-10% foot throttle, (im assuming IAC is dead here or huge injector leaks,etc )
if you now have spark, correct we now play fuel and air.
you are very welcome. !!!
other points, that can effect this.
1: cat melted (if there is one) nah.
2; iac STUCK CLOSED cold and is cold.now. , ISC DEAD.
3: EGR main STUCK OPEN
THE MAP Reading you gave was wrong, (that number) .
4: gross injector leaking, but pulling fuel pump relay and starting on test fuel proves this easy.
5: BAD FUEL, SEE #4 PROOF, AGAIN.
STARTing with no fuel, (first none if flooded, then test fuel) has great values for cause off flooding or loss of fueling .
it puts you at the right point , in diagnosis, so you save time and wasted parts $$$
good luck to you, and your new SAMMI
keep in mind flooding shorts spark plug tips , wet gas conducts electricity, well. making no spark or too weak.
KEEP BATTERY CHARGED,
or cranking long will lower spark energy.
What is the correct amount to see on MAP sensor?
