Question
saucerguy
oday 07:17 PM
It died all of a sudden, I was rolling fast enough to make it to a parking lot. To eliminate being a low fuel issue I put in a little fuel into the tbi, got it to sputter but not start up. It did that a few times then nothing.
Going down my list of new parts but to no avail. I do not have spark or fuel at this stage.
New fuel pump, fuel filter, tore apart and cleaned out top of tbi/throttle body, diafram in good shape to boot. Fuel pressure at the line, injectors tested fine, still no fuel.
New ignition coil, new secondary coil, new fuel pump module, new cap and rotor, new crank position sensor/detonation knoc,
It turns over thanks to a recent new starter, battery, alternator I put in a couple of months ago so it has the juice to create the compression.
The injectors are getting juice, they function and push fuel when I fed them when the top end of the tbi was out.
I'm stumped at this point. Any help would be appreciated
