Hi, Getting very frustrated, looking for fresh ideas before I blow a gasket.....sell the bloody car....or set it on fire! I have fitted a ST170 engine using Megajolt with original Ford Edis and coil pack. Everything was working, test drive down street was OK but the Dellorto twin 40's could not give enough fuel/air at idling and acceleration (jetted for 1.6). After speaking to webcon and pricing up parts I decided to order Twin 45 webers with 5 progression holes (specific for Zetec), fitted them and everything was running OK on test drive. Waiting for rolling road session, however after a trip to A&E with chest pains and a minor operation I had not touched the car. Returned back to car after 6 weeks the car will not start. I am getting fuel and spark, I have also tried another coil and changed spark plugs. Switching at coil OK with test light primary coil readings 1.3 ohms and Secondary coil readings 10.38, I believe within parameter. I have not touched any wiring, although next job is to make it tidy with cable covering. I do occasionally get back fire through exhaust and popping back through carbs, feels like timing, maybe over fueling. I have removed Megajolt plug and tried on Edis limp home settings but still no success. I need your help, what other tests can I do before starting fresh with ignition and fuel system?
