Went over a speed bump lost power.now won"t start.engine turns over but no spark.ckecked sensor plug-all ok

Is it setting any fault code in the Powertrain computer?

Will still run with bad speed sensor,check fuel pump.

I would start by checking the basics which are checking for spark and fuel. If you have a gauge, check to see if you have fuel pressure when the key is turned on. If you have fuel pressure, check for spark. Chrysler products are known for the crank shaft sensor to go bad and cause a no start. Also, if driving for a certain period with the pedal depressed at the same speed, the throttle position sensor will stay at that position if stuck and will cause either and driveability problem or stalling. You may wanna look into replacing or at least checking that. Good luck.

check your fuses and kick starter also check if there is a spark from the plug wire if there is no spark check your coil and the distributor i think the problem will be solve

You have got to isolate your problems one by one. Is your crank position sensor working? Yoiu can test it individually or you can plug in a diagnisis interface and crank enine in a raltime test mode and measure engine RPM. If sensor is ok you get revs recorded and you go to next step i.e getting spark at the plugs. The spark is also a series of wiring and interfaces so you start from ignition switch itself to the ICU, power output stage and coil packs. Once you have your spark then worry about the fuel.

Since you changed the sensor we will assume it is working. When you disconnect it you put the computer in limp mode which stops it from using sensor values. If code 300 is the only code we will assume the coolant temp sensor and others are ok.
I would check fuel pressure with a gauge next.

Hi Paul brad hear, if you have spark plugs working i.e. sparking and fuel coming into the engine something has got to happen, many not start but it would backfire cough because when those two things come together something always happens. OK The other thing that would keep it from starting, the timing change or gear has broken and the cam is not turning. Im not sure if the Tacoma has a chance or gears. good luck

you said you repl dist cap that means you don't have a crank sensor you have electronic ing module. remove your elec ing module have it tested most auto parts stores could test your module, or check your coil at the neg terminal. should have power. if not you lost your primary volt from your batt.your secondary power is coming from your electronic ing module from the module to the pos terminal on the coil, when the eng cranks,from the coil to the dist cap , from the dist cap center to the rotor then out to the plugs,this all happen pervided the timing belt or timing chain is ok. the cumbustion chainber needs 3 things , thats fuel, air, and spark.

could be a number of things......engines need spark fuell and air to run.....one of three in your case is not working correctly
try disconnecting fuel line from engine side of feul sending unit and turn over ....get a bucket it could get messy....if you see fuel then check spark...to check spark leave fuel disconnected....and pull out one plugs leave wire on plug and touch plug threads to ground (anyground..eg..alternator bracket)use vice grips but not too tight ..then turn it over again and see if plug sparks......if spark and fuel are present ....then ur into crank sensors or cam sensors these determine when spark is present.....

Hi there are few things that you have not check that can cause this problem,cap and rotor , pick up coil regular coil ,fuse (start with the less expensives) good luck
