EVP and EGR ?? (HELP!!)
I have a 92 F150 that won't start. Replaced plugs, cap, rotor, and ignition module without any success in tracking down the problem. The EEC is giving code #327 (EGR valve below minimum voltage). Before I go any further could someone tell me if this would really prevent the truck from starting? I have heard of people completely removing the EGR valve and never have a problem starting their vehicle.

EVP and EGR ?? (HELP!!)
Taking a guess here...
Some EGR systems have a solenoid that controls the action of the EGR. The computer on some cars will monitor the voltage pulses out of the sensor and may set a code.
Some have a Pressure Feedback Emitter, which is similar to the EGR Solenoid and appears to perform a similar function.
Don't know on an American Ford engine, but Japanese solenoids for things like SHOs and Villagers cost a bundle(over $100). A Chevy solenoid costs about $35.
Maybe the solenoid is failing? This is fairly common on a Chevy with say 80,000 miles or more.
Good Luck,
Jim Henderson

The EGR is not active during cranking, so that's not it, but my list says 337 is HIGH voltage at the EVP.

You should look for the 4 basic necessities of a gas engine: fuel, air, compression, & spark. A Haynes manual helps.

[updated:LAST EDITED ON 01-15-03 AT 07:13 AM (EST)]I too had a solid KOEO 327 code about a year ago. It did not stop the truck from starting. In fact the truck did not seem to run any different at all. I ended up replacing a bad EVP sensor. Use a Haynes manual to troubleshoot the EVP sensor with an ohm meter.

sirkiethc, I stopped off to help a fellow that his truck just quit running with no warning at all. I checked his spark and pushed down on the fuel rail relief valve and fuel came out, diagnosis fuel and spark it has to run but it still wouldn't start. we got it to a local shop and had it checked out and it did turn out to be the fuel pump. but it still had enough pressure to squirt out of the valve. So you might check your fuel pressure with a guage.
just an idea.
good luck.
