99 4X4 2.7L 5 Speed Manual, Hi Guys, I'm new to this Forum Thing, So Please be patient with a Newbe. This Taco was running fine until last week when The Son ran it out of gas. From there, couldn't get it to pick fuel back up. Fuel Pump gone, right? Replaced it and now it cranks only when it wants to. So, I plugged my ElmScan5 Up to see what might be going on. :nerd Imagine my Surprise, :surprise, the Scanner won't connect. Been a while since I used the tool, so I updated the software. From there I was able to get it to link up and scan, and what do U know, no codes set. Cleared parameters and code memory anyway, already here there. Next, turned the switch to try and crank just to see. Viola, it cranks up and runs strong! After checking O2 sensors and all else, I disconnect and shut her off. Unplug Scanner and button everything up. Now for a test drive, turn the key, no start. I have spark, fuel and and compression, so why won't it start? i know that it's in time, cause when she runs, she roars! Been seeing several threads on these Forums about others having issue with the MAF sensor. So I checked that, all is up to specs. could it be that the ECU has a bad ground and the Scanner is giving it an alternate route? Any and all Help from U Motorheads out there are Welcome. They say that 2 heads are better than 1, so what can we accomplish by putting all of ours together? Thanx Dogg:brickknoc
