3.4 Tacoma engine miss

check for compression. essentially you remove the EFI fuse/relay and put a in place of each spark plug then crank the engine (by hand or key) 1 cylinder at a time, and see if you get pressure to hold. if it does hold, your good. if the needle never moves. you have a problem with the valves of that cylinder. head rebuild time!

btw, the gauge should be reading around 180-200 psi per cylinder. if your not around there for all cylinders (less than 140 or not within 5% consistancy), you should take the heads in to be rebuilt.

 

Got her going today. Had a injector plugged an a brake caliper stuck not letting it pull. Thanks everyone for the help
