1986 Toyota pickup don`t start after one hour rest during winter.

Asked by pagemich Jan 04, 2010 at 01:33 PM about the 1986 Toyota Pickup

Question type: Maintenance & Repair

My 1986 Toyota pickup don`t start after one hour rest during winter. (In Quebec, it’s very cold   – 20 F.) No problem when warm, no problem when cold. When the problem occur, I got fire on plugs, but the fuel does’nt come. After it cool down, the engine start easely. I think that a sensor is in trouble. If it’s right, which once. If not, where should I look.

If your truck is fuel injected. It could be that the ECU (computer) is reading the coolant temp. and adjusting the air fuel ratio for an engine at that temp. That would make the engine run lean and not start. The only way that could be fixed is with a intake air temperature sensor, I dont know if one of those is avalible for you year of truck.
