Car starts only with gas pedel to floor but sputters than stalls within a few secs

Also if I donate for ya help once car is fixed do u get this or does it help u in anyway

My uncle said it said po121b with description ignition coil module 24x too many pulses I looked code up but it says crankshaft censor not the description the obo2 said so is it possible to have a code p0121b with the description that came after the code if not I'm just gonna have to have my uncle come back out with obo2 but everytime he wrote down the codes an what it said after code an he had that code with description wrote down twice that he brought the obo out to try the first time I had p0121b an p0335a after I replace crankshaft sensor one of em codes never came back but the other still remains an says ignition module 24x red curcit too many pulses

My auncle bringing obo 2 back out to see what the code is for the ignition module but you stated a few messages ago that compression would tell me how my timing was so since I got 150 each cylinder than my timing chain is fine the question I got is if my timing chain tentioner is worn an if the chain skiped teeth should the compression show that or does compression only show that the Chain hadn't broke basically would my car act like it does if the chain skiped teeth thanks for ya help

Ok bout to call my auncle to bring obo 2 out to check for codes again also im going to go buy a haynes book to check the tentioner an timeing chain let you know the code in a few

I have the obo 2 hooked up right now the only code that is showing is an it has a defition next to it saying igntion coil modulke 24x red curcut too many pulsesi I looked up the code p0121 but the definition I see online for it is says throttle position sensor/ switch a circuit range/ preformance problem so now I gave you the exact code the obo 2 is showing hope it helps but why would the the obo 2 tool show a diffrent defintion than what I find online an the obo 2 im useing is the one middle creek garage uses my auncle is one of the head mechanics there an the obo 2 is realy expensive a few grand I think an the update on it cost 1,400 it just got updated so while I got the obo 2 here an my auncle is here is there n e thing else I can be trying its hard to get my auncle to ever come look at it an my auncle out of ideals because everything he checks for turns out to be good

Well think I got the problem had plugs out an turns it over gas shot out the first three spark plugs holes I cleaned spark plugs put em back in took out fuel pump fues an tryed to start it with starter fluid an in the first time in awhile I got it to finally run as long as I kept spraying fluid it kept runing so guess my fuel injectors was flooding my car so bad it barely starts an an stall out because of all the fuel so what do I do now my injectors is getting pulse so do I need to replace the four I injectors or what

I haven't got back the obo tester to use again but I have a volt tester an do have the 5 volt going to tps an ground is also good still waiting for obo2 to do the other test on the tree but also what I found is if I disconnect the fuel pump fuse I can start car an keep car runing great by spraying starter fluid sprayed in air Intake as soon as I plug back in fuel pump fuse it than runs horribly for a few secs an stalls an spark plugs get covered in fuel

I had a similar problem and it turned out to be the idle air control valve. If this doesn't work properly you won't have the right air fuel ratio at idle.

My fuel pressure is 42 I cleaned off idle air control valve map sensor an still no change

I followed trouble tree an it has correct voltage with pedel to floor an when pedel isn't pushed all the wires look good do u think maybe it's just the computer or is that ok because voltage is correct my uncle ( head mechanic at middle creek ) gave up said it probly just throwing a faul code an the problem is injectors or computer an I don't know how to test injectors except with a noir light an it pulses so I basically been stuck not knowing what to do I followed the tree twice just to make sure I followed it right I got a question if injector stopes spraying a mist an is just squirting out would that thro a code is it possible it could throw a tps because it's looting to much gas in cylinders
