Martin, Check this when your going to crank and know it won't start right off. Jump 87 & 30 on the rpm relay connector and then see if it will start right up. There could also be a connection loose on the side of the distributor for the pulse coil. Also check the pulse coil cold or hot appx. 600 ohms. Last thing I would look for would be a cracked cap. Let me know John hervey << Annoying problem with my car: When the weather's damp, it just refuses to start - pops a couple of times on maybe two cylinders but otherwise just cranks. The most recent occasion it'd been under a cover and the engine was dry - it was just a typical gloomy damp cold english morning. We put a hairdryer on the distributor for 30 seconds and it fired up first time!!!! What on the dizzy should I check? It can't be much different from any other DeLorean. The cap and rotor looked like this when she was worked on last october >>
