inconsistent spark Options

[Gtguy22]

ok, so i changed my distributer, cap, rotor, and plugs. Trying to get this car back on the road, but my spark is inconsistent, literally some times i have it, sometimes i dont. What the hell is going on here?

[FunkySR]

could be a bad eartyh somewhere. oxydisation at some terminals?

[Gtguy22]

a bad what? eartyh? at this point im back to having no spark, very confused about this

[Spider77]

Bad ground. Thats what he means. So, back at this again? If all that stuff is new id guess distributor (but you put a new one on, right?), ignition coil. But yeah, check all your grounds and clean any corrosion.

i had two distributors, the one that came with the jdm engine, and the one from the old engine. I switched them. This is seriously a mystery to me. Ive checked everything, not getting spark.

[Galcobar]

How about the wires?

Is it a particular cylinder which isn't firing, or does the problem exist on all of them? If it's a particular cylinder, try swapping leads around to see if the problem moves with the wire.

igniter? loose wiring? loose pin/terminal in a connector somewhere?

the problem exists on all of them. Sometimes itll have a real strong spark, ill turn the car off, and it wont have spark the next time i start it up.

igniter? loose wiring? loose pin/terminal in a connector somewhere?

igniter? how could that be? and where is it? how can i check it? also loose pins/teminals in a connector, definitely a possibility, but how would i check that?

so after a week without looking at the car, i jumped back into it today, sanded and cleaned around all my grounds and checked them all with a light. the grounds are fine, im still not getting spark. this doesnt make any sense to me, i had it started last week, got spark, then turned the distributor to set the timing and lost spark. so i put it back where it was when i got it to start, and sure enough, no spark, no start. PLEASE HELP!!!

coil is on its way out... same thing happened to me... another thing to check is if there's ANY build up of oil in the plug wells (the tubes tend to leak...)
it will intermittently ground out our spark

[Gtguy22]

ill pick one up today and try it. thanks man, ill post later

[Gtguy22]

ok so ive never been more confused or frustrated. Seriously. Today i bought a new coil, installed it, and with a spark plug out, and the car hooked up to jumper cables, tada, she started. So i shut the car off, put the plug in, and tried starting it again. No spark. WTF!!!!!! Nothing changed between having spark and not having spark. So naturally i took the plug out again, and sure enough, no spark. What in gods name is going on here? Is it possible at all that the computer doesnt match up with the new jdm engine? woulld that cause a "sometimes spark"? Please help guys, im getting really fed up with this car.

also could it be timing? I had changed the timing belt as well, but i was able to get the car started numerous times after i had done the belt. Im so lost right now

are you using a 5s-fe ECU on a 3s-fe?..

[Gtguy22]

i am using the computer for the 5sfe. The one with the original engine. This jdm engine was supposed to just go right in without changing all this crap, it did not come with a computer, so the computer is the same one that was in the car. P.S if that is the case i am in big trouble. The wire harnesses did not match on the engines, i was told it was because the steering wheels are on the other side of the car in japan. I was told if i changed the intake manifold, and wire harness, basically use the new engine as a longblock, then everything would be crystal. Thinking about it now, if my car wont start because japan didnt make a 5sfe(if the computers arent the same) and i would have to get a 3sfe cpu, then the whole wire harness would have to be changed AGAIN. God i really hope that isnt the case

[Gtguy22]

in addition, i called the place i got the engine from Got-jdm.com The guy who originally told me the engine would drop right in, then told me to use it as a long block, basically just told me that if this was the case, i would have to pull the engine again, put all the old components back on, take off my timing belt and water pump, and all the other crap ive put on this engine, and send it back for my money back. thats absolutely ridiculous. Im in a mix right now. really hope i can get this damn car going

[Mstoochn]

what car did that engine come out of? if its a celica, its a 3s-fe 100%

[Gtguy22]

i was told it came out of a 94 celica 2.2 gt. Was supposed to be the exact engine for my car

o.0 then it cant be a JDM engine

[Gtguy22]

i know, thats why im thinking he sent me a 3sfe engine, or a camry engine and told me celica gtt. This was too much work to turn back. Im not really sure what to do

[bmj67]

if it started when you had it hooked to jumper cables try charging the battery for awhile
