My 1997 Mercury Tracer 2.0 automatic would sometimes bog then be fine. It now wont start. Before it died we pulled two codes one read P0351(coil) the scond one was P0300 (random misfire). We put new sparkplug wires and replaced the coil. On the test drive it did the exact same thing. We then changed the oil and thats when it wouldnt start up. We cleaned the crank sensor pickup and it ohmed the same as a new one. We cleaned it and still no start. It has fuel pressure of 38 pounds when cranking and doesnt leak down. We borrowed a noid light form a local auto parts. The only one in the set that would fit said geo so we used it and did not light for the injectors. There is also no spark to the sparkplugs. We check there is no power to the coil when the key is on.

As noted above we tryed all that. No noid light to the injectors. 38 pounds of fuel pressure. No spark. Crank Position sensor ohm'ed out the same as a new one. There is no power to the ignition coil with the key on. Engin spins over fine but it does not run. All fuses are good. Recently it had an intermittant problem with bogging and bucking under acceleration conditions. It made it home we changed the sparkplug wires because they were cracked. When it first started this problem it said two codes which were P0351 (coil) and P0300 (random misfire). The battery voltage checks out to 12.8 volts.
