Failed Fuel Injectors?

[RuSty420]

Hi,

My 1995 4runner, 144xxx miles, good condition just recently died while I was driving home from work. I was driving along slowly done a residential street when suddenly the engine died and went unresponsive. I had it towed to a mechanic who discovered several problems with it. The ignition drum and rotor needed replacing, the starter needed replacing, and 2 of the fuel injectors failed. Supposedly when tested, instead of injecting fuel at timed intervals they were releasing a constant spray of fuel.

The mechanic told me I should replace ALL of the fuel injectors even though only 2 had failed so far. His reasoning was that he thinks because 2 failed the others are prone to failure in the near future. Is this true?

Around how much would you expect a job like this to cost? (replacing 2, or replacing all)

Alldata is your friend and will pay for itself the first time you don't get ripped off.. Mechanics often bid the job out and get paid not hourly but by how many hours they turn. Most have a "magic pen" that adds additional labor, so they can get paid more for the job.

As far as costs go this is what alldata lists.

95 4runner:

3.0---Injectors- 2.7 hours for all of them
cap & rotor .7 hours
Starter: .7 hours Direct drive: 2.1 Reduction drive 2.2

2.4 Starter:.7 Direct Drive .8 reduction drive .9
Injectors: 2.9 hours
cap & rotor .5 hours

times the amount of hours by the hourly labor rate, then add the cost of parts and any so called "shop supplies" and tax. If the shop is being honest that should be the cost. Don't forget to factor in the DIAG.


As far as two injectors failing, that should have caused an extended crank and/or misfire while they where going bad. They typically don't just fail out of the blue and stop a vehicle from running. If your starter is bad the engine won't even crank over it would do absolutely nothing or just click. The engine would not turn over. They may just be adding this problem to the list for extra money if the engine cranks.
