No start 1996 2.7L

[matt922]

Hey guys I am new here, but not new to cars at all. Have been working on them for several years.

My friend has a 1996 2.7L 4runner, last weekend i changed plugs and wires for him because it was sputtering very bad and would just cut off without much of a sign. I installed the plugs and wires and he claimed it was running much better, drove it for 4 or so days and it had not cut out on him. The other night he called me and told me he was broke down @ 10:30pm. Offered to pick him up but he had AAA tow it to his house.

I go look at it today and confused myself more than i did help myself figure it out. I looked for spark by pulling a plug wire out and putting an old plug in..no spark. But then i take a look at the relays... the EFI(fuel pump) relay is quite warm when i feel around.


i guess what i am asking is, how often do coils and fuel pump relays last in these cars?

I know in cars like my older volvos, it is not rare for a fuel pump relay to go out after ~100k miles. Any other common things it could be? The car has 100k+ on it.

i dont belive it is a relay, on eletrical you cant compare toyotas to volvos, volvos wiring and eletrical SUCK!!! i have never heard of toyotas eletrical going out like that...


and you said it wasnt getting spark when u tested it... did u have the plug close to a ground when you tried it? if not it wont spark anyways.... pull a plug and see if you can smell fuel. test the spark again... try that and come back!

i want to figure this out

haha, older (-87) had wiring problems...not so much now. volvos are easier to work on, even with a turbo hangin off the side of the motor

when i pulled the old plugs, the were white as could be. I couldnt really find any ground within plug wire length of the wire, everything was bare aluminum or painted :bash:

it will be Saturday before i can get back to his house... i'll report back when i do.

 

[shootmymime]

volvos ha! yeah the couple i have worked on was fricking old

it really dosnt matter for bare metal.... it could be painted and it should get a good enough ground

 

[The Dude]

Volvos are awesome. I've had 2 of em in my time. An old 240 and a 740 and I enjoyed driving them almost as much as I like driving my 4runner.

Funny, I was just thinking this morning too, that maybe I should sell the 4runner and get a volvo as a daily driver, since I just picked up an 88 FJ62 to have as a weekend cruiser/trail runner/life-long project car.

do these cars have crank sensors?

 

[Mr. Dabadina]

my 6 cylinder was sputtering and I changed the plugs. Problem seemed fixed for a few days then back to sputtering for a day and then wouldn't start. It ended up being a clogged injector. Good Luck.

Is throwing a CEL?

it wasnt throwing a CEL when it was sputtering, but now i cant even see if it is throwing a cell because it wont even crank..(and i dont have an obdII scanner)

is the batt. dead now? is that why it wont crank? try jumping it for now...

err, i meant it turns over but doesn't run.

(CEL light is always lit until engine is running in most cars)

 

[matt922]

do these cars have a fuel check valve anywhere on them?

i didnt look at the car this weekend so i am trying to map out every variable and how i am going to deal with it

 

[shootmymime]

3 main things to get an engine running, spark, fuel, air.... and i bet everyone knows that... start from the beginging doing plugs so see if there is a spark..... then check if it is geting air, that an easy one... next is fuel (i know nothing about your engine... so i cant say if there is a check valve)

if everything checks out good... and you are getting air, fuel, spark.... BUT still not running, then its timming,


when was the timming belt replaced?

i would say thats what you have to go threw to see if it will start! good luck bud

Don't forget the 2.7 has a timing chain.

I had a Acura that had problems about starting, all of a sudden it would stop. I would get it towed and then it would start. The dealer put a new fuel filter in, distributor cap and a few other things, but it kept coming back. I thought it was the igniter switch, but it ended up being the coil. Still it cost me hundreds of dollars trying to figure it out.

When they act like this, it is quite hard to figure it out.
