But did you use your original fuel injectors, and all your original sensors? or did you use the ones on the new motor?
Ask Your Own Toyota Question
Customer reply replied 8 years ago

we use all origanal injector but except the crankshaft sensor since the new motor look like better condtion.

 

Toyota Mechanic: Tim Mohr, ASE MASTER TECH replied 8 years ago
The sensors on the JDM motors are all different, and the computer mapping is totally different, we do alot of the JDM motor, and we strip them down to the long block and use everything except the block and heads from the old motor, if not i have seen these not run,Tim

Customer reply replied 8 years ago

will chang c.s.s to orginal.no luck but funny thing is if i shoot starter fluid vehicle starts.for a few seconds.then cuts out when it runs out.so that means there spark but i think fuel problem.but if i disconnect fuel line at regulater fuel shots out.

 

Customer reply replied 8 years ago

forgot that coolant temp sensor got broken in process in installation.in process of ordering parts but will this cause all my problem.but why will it only start with starter fluid.

 

Toyota Mechanic: Tim Mohr, ASE MASTER TECH replied 8 years ago
You need to check all ground wires from the engine to the frame, if you are missing one, it will cause this problem, you have spark,and fuel to the rail, but no injector pulse, so also check for 12 volts to the injectors,tim

got power but no pulse when cranking
Toyota Mechanic: Tim Mohr, ASE MASTER TECH replied 8 years ago
Then you need to scan the ecm and see if you have cranshaft position signal and cam signal, can you do this?
