Re: fuel pump is getting no power????? Posted by RS [Email] ![]() ![]() ![]() In Reply to: fuel pump is getting no power?????, Jake W, Wed, 21 May 2003 12:49:27 Members do not see ads below this line. - Help Keep This Site Online - Signup |
With a 16-valve, the usual reason that the fuel pump doesn't get power is that the ECU isn't getting a pulse signal from the ignition amplifier indicating that the ignition is firing.
This can normally be from a few differnt things -
- Hall-effect sensor in the distributor has died
- Hall effect connector on the side of the distributor has broken
- Ignition module has bagged it.
- Contacts on the Fuel Pump relay have pitted so badly that there's too much resistance to get good power to the fuel pump (rare).
On an '85 it's rare that the ECU will die, but it sometimes happens.
'85s are also known for disintegrating insulation on the engine compartment wiring harnesses. It's possible that the ground wires from the ECU to the ground point on next to the AIC valve have died, but check the other stuff first.
Check ECU and Fuel pump fuses just for the heck of it.
Here's a link to Townsend Imports' page on LH 2.2 no-start conditions.
