Air, fuel, fire Posted by Ari [Email] ![]() ![]() In Reply to: Will not start. Turns over fine. Ran last night., izzy, Fri, 13 Jun 2003 05:15:44 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Three things you need to make the engine run.
Unless a squirrel crawled into the intake and died, air is probably OK.
From a post a while back:
Basics for both 900 and 9000, LH fuel injection-
1 - Look for air leaks - hoses off, cracked, broken. Check around the air
mass meter, intercooler and turbo (turbo models, 'natch)
2- Check fuses - on 900, check #30 (fuel pump), 22 (key on), 3 (coil
primary), for 9000, check check #14 (fuel pump), 13 (key on), 9 (underhood,
88-on) (coil primary)
3- Make sure you didn't run out of gas
4- Check for spark - does the tach needle bounce during start? If so, the
primary and ignition amp are working. If not, suspect the ignition amp.
To energize the fuel pump- open the fuse box, and jumper between fuses 27
and 30 (900) or 14 and 22 (9000). You should hear the pump run (this will
happen even with the key OFF). No noise, then check the wiring to the pump,
or the pump itself.
Do you hear pump noise, but the tank is less than half full? In some years,
the pump was two stage - the 'helper' pump worked for the lower half of the
tank. If the 'helper' pump fails, you won't get any gas with a half tank or
less. Add enough gas to get to 3/4 tank, and if the car starts, you need to
rework the aux pump.
Of course, pulling a spark plug or two always helps - if it's fuel wet, you know you at least have fuel, and probably no spark. No fuel wetness? Probably a fuel issue.
