I'm new to this forum and new to the tracker. I have a 95 Geo tracker 1.6l 4cyl mfi 8th digit Vin (6).
I bought the tracker with 230k miles so I anticipated I may need a replacement motor. The engine ran fairly well but leaks oil and burns oil and smokes a bit. I changed the oil and drove it for 2 days without issues. I was coming home today after driving 50 plus hwy miles. Around a 100ft from my driveway I slowed for a speed bump. After going over the bump the motor died. I thought I killed it by engaging the clutch to quickly but learned the motor just died unprovoked. No warning lights except the normal ones if the key is on and engine not started (oil, battery lights). My brother said he believes the oil is leaking from the intake manifold gasket. That's about everything I know about it. Please help!

Welcome to the forum. Does the engine crank or when you turn the key to start, does it do nothing? If it cranks, I would try spraying starter fluid into the intake (use the big brake booster hose, which is easy to get to). Can you get the engine started that way? If so, it indicates that your problem is with fuel, rather than spark.
Other than that, I would check your fuses, particularly the ig-coil fuse, which, if it’s blown, will prevent the engine from starting. Also confirm that your check engine light is on with the key on - that indicates the computer is online.
I don‘t know the history of the car, but all the vehicles from 1989-1995 have had issues with 3 capacitors in the ECU, which need to be replaced. If any of these capacitors are blown, the engine will not start. It’s not a big deal - a $5 fix - and most of us have had to do this. The ECU is behind the driver side front speaker - a bit of an adventure getting it out (and worse getting it back in), but you pull the ECU, open it up, and look for the big black caps with the X on the top - the 16v has two of them. If you can get in touch with the previous owner, ask them if they ever changed out the capacitors in the ECU.
You can deal with the valve cover gasket oil leak issue later....lol

Pete, welcome to the Forum, and what bad luck.

As Bex said, tell us exactly what happens -- and what you see and hear -- at each step as you turn the ignition key. Be as detailed as possible.

First off, thank you so much for the swift replies and valuable knowledge!
I will test those things asap.
When I get in the vehicle key in and ON it dings as it should. The oil, brake, battery and seat belt lights come on. No check engine light came on with key in ON position. When I turn key to start the motor it turns over and over and over as if I am out of gas but I have a full tank. When I stop cranking the motor the 4 aforementioned lights remain ON while key is in ON position.

Update: I tried cycling the key a couple times and I can hear the fasten seat belt alert but I can also hear another sound when turning the key ON position. It sounds like something turning on or engaging, almost like a soft click. It makes the same soft click when turning the key in OFF position. Is this the fuel pump making the soft click? I will test the starting fluid in the intake and the other things and repost an update ASAP. Thank you again

Update: I checked the fuses and my FI 15amp fuse was blown. I replaced the fuse and when I turned the key ON it immediately blew the FI fuse again. Any ideas on what could suddenly make the FI fuse blow while driving over a speed bump? That's what I was doing right before it died. I'm assuming this is my issue.

Thanks for the info. Since the fuse is blowing, it sounds like a smaller problem than a BAD computer -- been THERE, done THAT. I'm sure someone else can tell you what that fuse does on your Tracker which might solve everything -- HOPEFULLY.

On my '91, and probably yours, that is the fuse for the fuel injection system. That would explain everything, except how you can fix it. You might just be lucky.

I'm sure suggestions will follow shortly. Do you have access to any electronic testing equipment, like a voltmeter?

BTW, Is that a Suzuki bike in your picture? I have TWO Suzuki GS-550 bikes -- a 1977 & a 1978.

A short circuit in the wiring would be my guess - wire rubbing/chafing somewhere finally rubbed through the insulation, maybe a wire pinched somewhere - I believe the MPI models are known for problems with the injector harness chafing, Bex is probably the best person to confirm.

Pete,
How many 15A fuses do you have? You can always use one from another 15A non-essential accessory circuit, but you might end up going through a few during the testing process -- but much cheaper than a new fuel injector!

The FI fuse runs the main relay, which will be the black relay that’s mounted on the ECU (and next to a green relay that looks exactly like it, which is the fuel pump relay). You can easily test if it’s the relay itself that’s causing the problem by putting the green relay in its place, and turning the key to the on position. I would expect that the fuse will still blow (as I would assume that this is a wiring problem), but on the off chance that the fuse doesn’t blow, it would confirm that the relay itself is the problem. Note, of course, that the engine still will not start, without the fuel pump relay.
The FI circuit runs throughout the car, via the blue wire with the black tracer.
Post #2 will help you here. It identifies the components, and also recommends using a 12v test light, which will save you a box of fuses.

That sure is different from my '91 -- which has the main relay as a 20A (#13). Since Pete mentioned it was a 15A FI (Fuel Injection) fuse which matches mine 15A FI (#14), I assumed that was the problem -- as opposed to the main relay.

Look at your fuse cover. The fuse next to your FI fuse, which you are stating is for the ‘main relay’ - is actually the 20 amp fuse for your RWAL.

I am looking at my fuse box cover and at the FSM. The #14 fuse is marked "15A FI" -- for fuel injection.
Next to it is the #13 fuse marked "20A RWAL" -- for main relay.
Pete says in message #6 that he blew the 15A FI fuse, not the 20A RWAL fuse.

In my FSM it says "13 RWAL MAIN RELAY" which is a 20A fuse.

98212


Pete is referring to the #14 fuse -- 15A FI.

They both say "MAIN RELAY" in the FSM so that is probably the confusion here, but Pete said the 15A FI fuse blew. The FUSE BOX cover does not say MAIN RELAY for either.

Geesh. Yeah its for the REAR WHEEL ANTI LOCK BRAKE computer. It has NOTHING to do with the main relay that runs the main ECU

Best of luck Pete! Make sure to ask your question(s) perfectly!
