Have Toyota Questions? Ask a Mechanic for Answers ASAP
Hello and welcome to just answer and allowing me to assist you. Just a questioin you didn't by accident jump the battery backwards did you? check the engine fuse on the interior fuse block.
it will be marked ign fuse inside driver's side of dash , so was it jumped in reverse? if so you may need to check the 120 amp fuse under the hood battery side fuse block.
here are the location and fuses needed to check
yes the ones attached to the battery are the ones most likely to blow they are high amp fuses the older models used to have fuse able links there that done the same thing to protect the circuitry. check those.
a code reader just tells you if you have a trouble code and it's number so you can further diagnose that area of concern . No you can't check the ECU with it or the fuel system but I can tell you how to do that.
that sounds weird . take out the spark plugs and tell me if they are wet or dry
I don't mean to argue or second guess you but have you done a load test on the battery if it doesn't have at least 9-10 v reserve going to the electronics it won't operate properly. I have seen batteries turn engines over good but no reserve to do anything else .If you say there is fuel getting to the rails and plugs dry perhaps the ECU is not getting enough power to open the injectors.when you said th spark plugs are firing what color is the spark?
ok thanx just eliminating things .ok the spark plugs remain dry after cranking , disconnect one injector and check for trigger voltage as you crank should be between 2.5 and 5.0 v
well you said the plugs were dry after cranking that long? then it must be not getting fuel, there are a couple things you can do to pinpoint this. using a long thin screw driver with one end touching the top of an injector and the other end handle end tight to your ear have someone crank the engine and listen for a sharp clicking noise.the other thing you can try is spray a little quick start into the intake hose while cranking to see if it tries to start , tell me what happens doing these two things.
ok then we need to check the fuel pump pressuer should be over 30 psi
Good I BELIEVE WE ARE VERY CLOSE TO SOLVING THIS
LOL THAT'S WHAT WE'RE HERE FOR , CHEERS
now were getting closer to the problem. can you take the line coming from the fuel tank off at the fuel filter and see if it pumps better there before it goes through the fuel filter? that will eliminate the fuel filter.
here is a link that may help you pull the filter but you mau want to jump the fuel relay first to see if that makes any difference. http://www.scionlife.com/forums/xb-tech-diy-1817/fuel-filter-replacement-93840/
