Cranks but will not start,backfires through carb./acts like timing is way off while cranking, has a manual trans.-can drift start and it will run fine, may be ok for a month and then acks up again. Have checked timing, replaced ig. module, dist. pickup, coil, carb.

Is there a cel ( Check engine light ) lamp lit ?<o:p></o:p>
Is it missing under a load ?<o:p></o:p>
When if ever has the plugs and wires been replaced?<o:p></o:p>
Loosing power ? Fuel pump related issues<o:p></o:p>
<o:p></o:p>
<o:p></o:p>
There are a few possibilities to start off with:<o:p></o:p>
<o:p></o:p>
1: Crank position sensor, with your year model, it’s most likely in the distributor.<o:p></o:p>
<o:p></o:p>
2: bad plug wires<o:p></o:p>
<o:p></o:p>
3: bad plugs<o:p></o:p>
<o:p></o:p>
4: fuel filter ?<o:p></o:p>
<o:p></o:p>
5: fuel pump intermittent problem.<o:p></o:p>
<o:p></o:p>
6: stuck EGR valve. CEL only<o:p></o:p>
<o:p></o:p>
7: processor ground and power supply, check connections. CEL may not illuminate.<o:p></o:p>
<o:p></o:p>
8: Map sensor. CEL only.<o:p></o:p>
<o:p></o:p>
If there is a CEL lamp illuminated you’ll need to retrieve the codes, If there is no CEL lamp, then try the other possibilities.<o:p></o:p>

Good luck……….. Chongo <o:p></o:p>
