Been following this post. I think whats going on here is--your camshaft is installed one tooth off on it's timing.
I would go back to basics here: Pull the valve cover and rotate the engine until you can line up the line/dots thing on the cam front bearing, straight up in the 12 0clock position. Then look down at the crank timing that should also be at 0 TDC. This means timing is set for #4 piston. Make sure at this position the rotor is pointing to #4. You can't get the distributor in wrong because of it's alinement slot that lets it only install one way. Move the wires in the cap if necessary to point to #4.
If you can't get both these marks (the cam and the crank) to align exactly you are off a tooth or two. I would check this before spending any more time/money.
It sounds like you adjusted the carb the proper way so you are probably good there.

It's been many years since I had a 1.9 dizzy out but I think the alignment slot will allow it to be installed two ways, one 180 degrees from the other.

Thanks egg and oldestisuzuist for the info. Although I am frustrated like nobody's business, this site and Isuzupup.com is helping me out a bunch and I greatly I appreciate it. This weekend I will go ahead and remove the valve cover and do as recommended. I will keep you all posted on what i find.
Thanks again.

Unless the 1.9 is different than the 1.8 the slot is slightly off to one side so it should only let it engage one way.

same as the 1.8 im using a 1.9 dizzy on my 1.8

I went ahead and removed the valve cover.
Marked the body of the dizzy where the #4 on cap is.
Aligned mark on pulley to 0 degress TDC.
2 dots on the camshaft were at the 12 oclock position.
Rotor is pointing to #4, aligned with mark on dizzy body.
Rewired my spark plugs accordingly.
Since rotor was pointing to #4 i put my wire according to dizzy cap.

Does not run . It cranks but does not run. I moved the dizzy body to try to make it start but no luck. If i put the spark plug wires opposite of each other, #1 wire on #4 dizzy cap, it starts right up and runs but my timing mark is still way off somewhere in the driver side. Timing it w the #4 wire looked the same. I still dont have a clue of whats going on. This is more confusing now.

Anything else i can do????

Well even though i was looking at the wrong marks on the cam, it is still wrong with the correct marks. They do not line up. Since this engine is from surefire, which i bought from autozone, I will be calling them up and hopefully have them fix this issue. I have a 3 year warranty on it. I will keep you all posted on what happens. Thanks again for the help guys.

Marcos

I believe you nailed it. Yes the cam timing is wrong. Forgot that there was more than one mark on the cam as it has been a few years. As I recall my 79 had a triangular arrow that pointed to a line on the cam indicating #4 timing. I would have them correct it and also suggest they refund some money for all your trouble.
Lets us know the outcome.

Update: I took my Pup to a couple of mechanics to check it out. One said that the marks on the camshaft where not important and somehow "tuned" my truck that I could barely go 60. I then went ahead and took it to another mechanic in town and said that I had my vacuum advance for the dizzy wrong (I had it hooked up to the carb) so he placed the vacuum advance on the intake manifold near the valve cover. Both mechanics disregarded the marks on the cam even after I explained it to them When test driving it, I noticed quite a bit of blue smoke coming from the tail pipe and a bunch of blowby from the valve cover breather . After talking with the engine builder, he said to do a compression test, dry and wet. My numbers where low and spark plug #3 was coated with oil. Emailed the engine builder and I will be getting another rebuilt engine here pretty soon, free of charge. So I am hoping this engine is built right and these issues will not be present. Thanks again guys for the help I will keep you all updated.

Marcos

Wow! I can't believe your bad luck with mechanics. About the cam timing marks not being important---what a load of BS.
Also the distributor vacuum advance IS connected to the carb, NOT the manifold unlike what the mechanic says. I would stay away from that place for sure.
And yes, they owe you a new engine for sure. My opinion.

at least you going to be getting one that they will make sure is right this time around

Yeah, ever since I bought this truck I have had all sorts of bad luck with it, but I'm not one to give up that easily from the info you all have given me, I thought I did everything right, I guess those two mechanics don't know much about these little engines, either that or they didn't want to deal with a 25 year old truck I am hoping that my luck will change soon and that the engine they are going to be sending me will work like it should. I will keep you guys updated

Marcos

mine has given me a bunch of problems as well but i just can get rid of it
when something breaks its an excuse to replace it with something better

Small update
I received the other engine and checked the timing marks before I put the engine on the truck. I did as you guys said and placed the crank mark (harmonic balancer) on 0 TDC, checked the cam marks and they were off!! I couldn't believe my luck. The timing marks on the cam were at the exact same spot as the other engine. A buddy of mine who works for Toyota checked out the engine, we made sure the chain was correct, which it was, and he told me to check the harmonic balancer. Went to the junk yard, got one from a 1980 luv G180, which the balancer is smaller in overall diameter (5 1/2") placed it over the isuzu pup balancer (aligning the keys) and........wait for it......... the notch on the balancer lines up with 0 TDC and cam marks line up. Instead of removing the balancer from the isuzu pup and risking ruining the seal, I marked a groove on the balancer and will be using that to time it.

I hope to get the engine in the truck soon and have it running and hoping for the best

P.S. - I measured the pup's balancer and the overall diam is 5 3/4" and the luv's is 5 1/2"
Im guessing the engine builder used a luv balancer to time the engine.
