HELP! Car wont start after Wires/Cap/Rotor replaced WTF!?!!!! - Toyota Nation Forum : Toyota Car and Truck Forums

wantamr2 · 04-17-2005, 09:49 AM

I just spent the day replacing the Cap, Rotor (OEM) and a set of MSD wires to replace the old tired nologies and now my car wont start!!! While i was i nthere I cleaned and oiled the KN filter. At first I thougt because I forgot to replug the MAF (I didnt unscrew anything just pulled the black plug by hand on the intake) was the issue but when I plugged it back in it still wouldnt start!! Do i need to reset something?

I double checked everything along with the firing order of the wires were correct. The car will turn perfectly when the ignition is turned but the engine wont start!!! It actually seems alot stronger when the engine is turning after the tune up but for the life of me it will not fire up. I am pretty sure spark is there if it is firing. Someone please help.

Iwas told the cap may be off but it was put in exactly as it came out. Anyways how can I get it on wrong if it has holes to line up for the screws? Someone mentioned I should try manually turning it but not sure how this is done if its screwed in?!?!?

make sure your AFM plug is on there properly and also triple check your wires on your cap and check the connection of the coil wire.

Did you change your wires one by one to make sure you replugged them in the right place??? or did you just change them thinking they just plug anywhere??? I did that the first time I changed my own wires..

that happenned to me on my 87 mr2, it turned out that my wires were wet and they got the plugs wet so I got a blow dryer and dried both ends of the wires and the spark plugs, it worked fine after that... I too thought it would be the AFM or something. Hope that helps GOOD LUCK, Jon

i like using CRC 656 in the cap and a little spray in the dizzy before the cap goes back on doesn't hurt.

I checked everything over. The cap is numbered so its pretty straight forward. The cylinder fire order for the 3SGTE is 1,2,3,4 starting from the right (distriubtor side) to left (intercooler side). I made sure there was spark from the coil as I was able to arc it easily. The rotor is tabbed so it can only be put in one way. Timing wasnt touched as I was careful not to move anything (its takes a little force to actually move the distributor). The cap goes in one way and the holes need to line up. Anyone have any other ideas?

That is 100% wrong.

#1 is closest to the intercooler.

#4 is closest tot he transmision.

it might be a PITA, but i would try to replace the cap/wires/rotor with the old stuff to see if it replicates either no-start or a start condition.

JekylandHyde · 04-18-2005, 10:43 AM

TTG ... se my last post ... he has them in the wrong order.

ToyotaTechGeek · 04-18-2005, 10:59 AM

yeah, jeff! we must have posted at the same time! LOL!!!

plus we all know, i DON'T KNOW JACK ABOUT MkII's!!!

Not to be a pain, but the "firing order" is 1-3-2-4 for the 3S-GE, 3S-GTE, 3S-FE, and 5S-FE. Toyota V6's usually fire sequentially from 1 to 6.

And it's no wonder it didn't start ...

. It was trying to fire 4-2-3-1.

So is Hyde right or are you? when you say 1-3-2-4 is 1 starting from the distributor?? Confused here...then again it doesnt take much.

Jeff is right, but so am I. The main reason it's not starting is the position in which you plugged your wires. Cylinder 1 is closest to the cam gears or intercooler if you prefer, while cylinder 4 is near the distributor. Looking at the engine from the back of the car with the Toyota labels (on the valve cover and intake manifold) facing you, it goes 4, 3, 2, 1 from left to right. So, the wire at the distributor was plugged into the slot for cylinder 1 when it was actually in cylinder 4's spark plug hole.

The actual firing order is 1-3-2-4, not the layout. By having 4 plugged into 1, 3 plugged into 2, 2 plugged into 3 and 1 plugged into 4, you effectively reversed the firing order. Hence, 4-2-3-1, and therefore absolving the engine's ability to run.

Toyota's explanation if needed

I was talking about the physical order of the cylinders/plugs.

Jason was talking about the order in which they get zapped
