Engine Performance problem
1992 Mazda Truck 4 cyl Four Wheel Drive Manual 110000 miles
1992 Mazda b2600i: After the truck has been parked for more than 2 or 3 hours I have to crank the engine as well as pump the accelerator in order to get it to start. Truck is fuel injected so that one is hard for me to figure out. The longer the truck is parked the longer I have to crank it to get it started. Here's the kicker: Once the truck is started (after about 10 to 15 seconds of rough idle) the truck runs perfectly AND once it is warm it starts right up after turning off the ignition. I have performed 1) fuel pressure test: goes up to 45 while cranking 2) fuel volume test: passed 3)plugs replaced even thought the plugs in the truck show only normal wear 4)OBD2 shows no codes. I unhooked the MAF to force a code and it showed up so the ECM is reporting at least THAT code. Any ideas?
